::: No, it doesn't require an environment of precisely 1g, it relies on the fact that the effect of local gravity is well understood, can be measured precisely, and compensated for. It's a fundamental aspect of the Kibble balance and you can rest assured that it hasn't been overlooked by the physicists designing it!

::::Oh really? ''How'' would one precisely measure the local gravity? In kilograms of force? No, sorry. This is a bad method. It leads to an insoluble quandary & clearly either ''hasn't'' been thought through by its supporters, or is an intentional exploit. ''Actually'' fixing it to Planck's constant would be great, but a Kibble scale can't do that. Weighing mass against anything but another mass is foolish.[[User:ProphetZarquon|ProphetZarquon]] ([[User talk:ProphetZarquon|talk]]) 22:15, 19 November 2018 (UTC) | ::::Oh really?

:::I'm very happy that measuring a kilogram accurately now may require EM shielding. EM shielding is far too rare nowadays, in this modern world of far-beyond-van-eck-phreaking. Anything that makes shielding more prevalent and widely understood is sorely needed.
