minus-square@[email protected]linkfedilinkEnglish18•10 months agoWelcome to engineering, where we have MPa as a unit of stress and mm/mm as a unit of strain!
minus-square@[email protected]linkfedilinkEnglish2•9 months agoWhy km/h (or mph) and not ft/year? Because the numbers have a nicer magnitude then.
minus-square@[email protected]linkfedilinkEnglish7•9 months agoDoesn’t apply here, say for example i have a piece of steel with length 100mm and it stretches 10mm, is mm/mm the strain would be 0.1 mm/mm, in meters it would be 0.1m/m Really strain is dimensionless but occasionally people add units
minus-square@[email protected]linkfedilinkEnglish3•9 months agoI feel like I should’ve spotted that… they’re the same units. 🤦
minus-square@iAvicennalinkEnglish2•9 months agoI was told that you also sometimes have four basis vectors in 3D

mm/mm?? why not call it m/m?
Because we’re precise!
