minus-squareBurstar@lemmy.dbzer0.comlinkfedilinkarrow-up9·1 year agoI’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?
minus-squareCarnelian@lemmy.worldlinkfedilinkarrow-up6·1 year agoThe official definition is actually 2.54cm lol
minus-squaredandan@kbin.sociallinkfedilinkarrow-up8·edit-21 year agoTo 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
minus-squareStumblinbear@pawb.sociallinkfedilinkarrow-up4·1 year agoIt’s just very stable and consistent, iirc

Why is it based on cesium?
