Converting to Metric
According to River, "adequate" vacuuming systems drain the human body at about half a liter per second.
Title text: According to River, "adequate" vacuuming systems drain the human body at about half a liter per second.

Explanation

Most people will eventually develop an intuitive feel for how big certain measurements are (e.g., how long an inch or a foot is, how much a pound weighs). This comic points out that people who were brought up using the imperial system probably don't have the same intuitive understanding for metric units and attempts to provide some benchmarks for these people. Most of the benchmarks are common sense, highly-useful ones (e.g., if it's 30 degrees centigrade, you'd be quite comfortable outside dressed for the beach) but some of the benchmarks are humorous and/or completely useless. Benchmarks include:

Temperature

  • -20⁠℃ - FuckFuckFuckCold and -30⁠℃ - Fuuuuuuuuuuuuck!: This is basically what some people would say when they step outside at this temperature.
  • -40⁠℃ - Spit goes "clink": The temperature at which your spit would freeze before it hits the ground.

Length

  • 1 cm - Width of microSD card and 3cm - Length of SD card: Refers to the memory cards used in cell phones, digital cameras, etc.
  • 1 m - Lightsaber Blade: Refers the weapon used in the Star Wars movie franchise. Canonically, the length of a Lightsaber's blade varies greatly depending on the setting of the weapon, but "one meter" is by no means a bad approximation.
  • 170 cm - Summer Glau: Refers to the height of the actress who portrays the character River Tam on the TV show Firefly.
  • 200 cm - Darth Vader: Refers to the height of the main antagonist from Star Wars.
  • 16 m 4 cm - Human tower of Serenity crew: Again, this refers to the Firefly TV show, which takes place mostly on a space ship called Serenity. Presumably, if all the crew of Serenity were stacked on top of each other, this would be their combined height. The comic depicts four characters from the show standing on top of each other; the bottom figure is the crew's captain, Malcolm Reynolds in his signature coat.

Speed

  • 110 kph - 30 m/s - Interstate (65 MPH): Refers to the American highway system.
  • 120 kph - 35 m/s - Speed you actually go when it says "65": People routinely break the aforementioned speed limit.

Volume

  • 30 mL - Nasal Passages and 40mL - Shot Glass: The comic points out that you could just about fill a shot glass using the mucus from your nose. Since shot glasses are usually used for mixed drinks, the comic jokes that this mucus could constitute a new, disgusting drink.
  • 3 L - Two-liter bottle: Refers to a bottle which contains two liters (in the US usually soda). There is debate as to the reason for the discrepancy in volume.
  • 30 L - Milk Crate: Refers to a type of small box originally used to transport milk but now often in demand to be used as bicycle basket, storage spaces, etc.
  • 55 L - Summer Glau: Again, this refers to the actress from Firefly.
  • 65 L - Dennis Kucinich: An American politician belonging to the Democratic party, noted for his relatively strong (for the US) leftest views.
  • 75 L - Ron Paul: An American politician belonging to the rival Republican party, noted for his strong rightest views. As hinted at in the comic, he, Kucinich and Glau would not get along at all well together trapped inside a fridge.

Mass

  • 3 g - Peanut M&M: A small chocolate candy
  • 5 kg - LCD Monitor: A modern flat-screen-style monitor.
  • 15 kg - CRT Monitor: An older-style, cathode ray tube-based monitor.
  • 4 kg - Cat and 4.1 kg - Cat (With Caption): Refers to the internet's love of putting captions on cats. Usually, this is done in a graphics program, but here the cat is actually physically carrying around his caption. The "with caption" part is most likely a reference to Comic 262, where Black Hat glues captions to cats.
  • 150 kg - Shaq: Shaquille O'Neal, a famously tall basketball player.
  • 200 kg - Your Mom, 220 kg - Your Mom (incl. cheap jewelry) and 223 kg - Your Mom (also incl. Makeup): Refers to a common type of joking insult whereby someone insults someone else's mother in a creative way. Here, the comic slyly calls your mom fat and implies she wears way too much jewelry and almost 7 pounds of makeup.

The title text refers once again to Summer Glau's Firefly character, River, who (after being subjected to a long series of medical experiments) is severely mentally ill and often comes out with macabre—though scientifically accurate—pronouncements.

Guide to Converting to Metric
The key to converting to metric is establishing new reference points. When you hear "26 degrees centigrade", instead of thinking "That's 79 degrees fahrenheit" you should think, "that's warmer then a house but cool for swimming." Here are some helpful tables of reference points:
Temperature:
60 degrees centigrade - Earth's Hottest
45 degrees centigrade - Dubai Heat Wave
40 degrees centigrade - Southern US Heat Wave
35 degrees centigrade - Northern US Heat Wave
30 degrees centigrade - Beach weather
25 degrees centigrade - Warm Room
20 degrees centigrade - Room Temperature
10 degrees centigrade - Jacket Weather
0 degrees centigrade - Snow!
-5 degrees centigrade - Cold Day (Boston)
-10 degrees centigrade - Cold Day (Moscow)
-20 degrees centigrade - FuckFuckFuckCold
-30 degrees centigrade - Fuuuuuuuuuuck!
-40 degrees centigrade - Spit goes "clink"
[Stick figure next to last three lines.]
Man: Pthoo [Man spits.]
Spit: Clink! [Spit bounces off ground.]
Length
1cm - Width of microSD card
3cm - Length of SD card
12cm - CD Diameter
14cm - Penis
15cm - BIC pen
80cm - Doorway width
1m - Lightsaber Blade
170cm - Summer Glau
200cm - Darth Vader
2.5m - Ceiling
5m - Car-length
16m4cm - Human tower of Serenity crew
[Human tower of Serenity crew stick figures depicted taking up from second line of panel to bottom.]
Speed
5 kph - 1.5 m/s - Walking
13 kph - 3.5 m/s - Jogging
25 kph - 7 m/s - Sprinting
35 kph - 10 m/s - Fastest Human
45 kph - 13 m/s - Housecat
55 kph - 15 m/s - Rabbit
75 kph - 20 m/s - Raptor
100 kph - 25 m/s - Slow Highway
110 kph - 30 m/s - Interstate (65 MPH)
120 kph - 35 m/s - Speed you actually go when it says "65"
140 kph - 40 m/s - Raptor on Hoverboard
Volume
3mL - Blood in a fieldmouse
5mL - Teaspoon
30mL - Nasal Passages
40mL - Shot Glass
So when it's blocked, the mucus in your nose could about fill a shot glass.
[Image of a shot glass.] Related: I've invented the worst mixed drink ever.
350mL - Soda Can
500mL - Water Bottle
3L - Two-Liter Bottle
5L - Blood in a Human Male
30L - Milk Crate
55L - Summer Glau
65L - Dennis Kucinich
75L - Ron Paul
200L - Fridge
[Cueball shoving Ron Paul, Summer Glau, and Dennis Kucinich into fridge.]
[Above fridge, circled, is 55+65+75<200]
Mass
3g - Peanut M&M
100g - Cell Phone

4kg - Cat [Drawing of cat.]
4.1kg - Cat (With Caption) [Drawing of cat, going "Mrowl?", and holding a caption.]
60kg - Lady
70kg - Dude
150kg - Shaq
[Stick figure of Megan and Cueball beside previous 3 lines.]

Why is 3L a two-liter bottle?75.69.96.225 21:16, 28 April 2013 (UTC)

Because this is America and we supersize our sodas! 72.68.9.56 (talk) (please sign your comments with ~~~~)
It is the volume of the bottle itself. I have added this explanation. Sten (talk) 22:39, 29 August 2013 (UTC)
A 2L bottle doesn't take 3L of space, not even close. I also think it's a reference to overly large drinks in the US. But even if it isn't, the current explanation is wrong. 108.162.229.34 22:28, 12 December 2013 (UTC)
I suspect he's just messing with us, because the approximate volume of a two-liter bottle should be obvious. Many beverages sold in the US are already labeled in metric. Soda is routinely sold in one and two liter bottles, with three-liter bottles common in some markets. Bottled water is often sold in liters and half-liters. Liquor and wine are sold in 375 and 750 mL bottles. Also, since 1 quart = 946 mL, an approximate (+/- 5%) mental conversion from quarts to liters is already quite easy. Fryhole (talk) 01:35, 25 January 2014 (UTC)
Yes. He is just joking. The name of the bottle contains its volume. The 3 liter measurement is a joke. It would be like saying a cup has 2 cups of volume. flewk (talk) 01:58, 4 January 2016 (UTC)

The world record as per wikipedia (and Guiness) is "only" 56.7. See corrected explanation above. Kynde (talk) 17:03, 6 March 2014 (UTC)

There was an incomplete asking for checking all measures and also for making sure that the references to serenity and velociraptors was mentioned. I did this, the last two by assigning the categories (firefly), and then also creating a new category:Your Mom. I now consider this explanation complete. Although if someone will speculate two whom the remaining two from the Serenity crew tower then please do so ;-) Kynde (talk) 17:03, 6 March 2014 (UTC)

This sentence in the 'Mass' section has a [small] error: 'This is a common theme in XKCD.'-- it should be 'xkcd', not 'XKCD'. See the website for Randall's personal opinion on this. Anyways, it's small, but kinda stands out if your a reeallyy hardcore fan. 173.245.55.73 05:39, 9 April 2014 (UTC)

Thanks for your hint, an update is done. But please add your comments here at the bottom. --Dgbrt (talk) 21:26, 9 April 2014 (UTC)

-40 degrees centigrade is also -40 degrees Fahrenheit! The only such temperature.--DrMath 07:51, 7 July 2014 (UTC)

kph got me confused, because "km/h" is the usual way of displaying kilometers per hour. 162.158.90.212

As a Maine resident I concur with this sentiment: "at -30°, the user is incapable of closing their mouth after starting the first "fuck", and so extends it into one long one." However, try uttering the word "fuck" without closing your mouth... uck-uck-uck... Npsych (talk) (please sign your comments with ~~~~)

13kph is not a typical jogging pace. At least I hope not. That would make me depressingly slow. 162.158.150.100 (talk) (please sign your comments with ~~~~)

The whole point of this comic

I thought the whole point of this comic was NOT to think in terms of non-SI units. The only reason (we) Amercans cling to customary/imperial units is because when some quantity of something is expressed in SI units you may as well tell them it's however many quatloos, because the average American has no idea what the units are like...nothing to which to compare that item. Approach learning SI units EXACTLY how you learned customary units: pick up a kilo (pound) and feel how much Earth's gravity tugs on it, stick your hand out in the outdoor air and feel what the NWS or a thermometer tells you what the C (F) temp is, eyeball a meter (yard) stick and try to remember how long that is, and so on. You're only hamstringing yourself by constant numeric conversions to some other system. For example, just accept a cm is a cm, and DON'T WORRY about how big that is in any other system. IMHO it is counterproductive to have the customary units (the conversions) in this explanation, and ALL of them should be removed. -- RChandra (talk) (please sign your comments with ~~~~)

Objection: In Australia are bottled drinks are 600 mL. --162.158.2.222 00:45, 6 March 2016 (UTC)

Was it really necessary to say 'Season 1' when talking about Firefly?  ;_; 108.162.219.68 04:10, 4 May 2016 (UTC)

Anyone know if there's something like this comic for learning Customary when you're used to Metric? I have a European friend with an American copy of D&D 5th edition that's tasked with DM'ing on short notice. 162.158.122.144 21:43, 26 January 2017 (UTC)

25 m/s is 90 km/h, not 100 km/h as stated in the comic. Is this also supposed to be a joke? 162.158.222.46 (talk) (please sign your comments with ~~~~)

The inaccuracy is mentioned in the explanation. And please sign you comments.--Dgbrt (talk) 20:48, 25 September 2018 (UTC)

23 degrees is a more comfortable value for room temperature. It also gets used in school physics questions, where we were allowed to convert it to 300 kelvin. (Sorry, but 26.85 degrees is too warm for a room.)162.158.39.41 16:58, 14 October 2018 (UTC)

It does not get to -40 in Moscow, however. It did once, like in the 1940s, but even then it was a temperature record. Now, with all the global warming business, -10 is indeed a cold day. In the more northen cities of Russia, like Murmansk, the "spit goes clink" temperature is possible.
