* albeit with a ±6 inch differential depending on local air temperature; as the Eiffel Tower is built out of cast steel, it expands according to how much heat builds up in the metal, which in turn is derived from the intensity and daily duration of the Sun's energy. It can also be argued that the number given above is due to rounding, and at sub-millimetrical lengths, the tower's exact height is fluctuating constantly as a result of the aforementioned thermal expansion. | * albeit with a ±6 inch differential depending on local air temperature; as the Eiffel Tower is built out of cast steel, it expands according to how much heat builds up in the metal, which in turn is derived from the intensity and daily duration of the Sun's energy.
