    I’m thinking, if we’re sharing pedantic data and the SI unit of distance is the metre, isn’t the inch technically defined as exactly 0.0254m?

      To get even more pedantic…

      It’s defined on how far light will travel in a vacuum in the time it takes caesium-133 to do a certain number of transitions between hyperfine ground states.

      It’s cool how almost all units of measure are defined on caesium
