minus-squarenooneescapesthelaw@mander.xyzlinkfedilinkEnglisharrow-up12·6 months agoWelcome to engineering, where we have MPa as a unit of stress and mm/mm as a unit of strain!
minus-squarecaptainlezbian@lemmy.worldlinkfedilinkEnglisharrow-up2·6 months agoBecause we’re precise!
minus-squarebleistift2@feddit.delinkfedilinkEnglisharrow-up1·6 months agoWhy km/h (or mph) and not ft/year? Because the numbers have a nicer magnitude then.
minus-squarenooneescapesthelaw@mander.xyzlinkfedilinkEnglisharrow-up4·6 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-squarebleistift2@feddit.delinkfedilinkEnglisharrow-up1·6 months agoI feel like I should’ve spotted that… they’re the same units. 🤦

That’s pressure.
Pushing down on me.
Pressing down on you.

mm/mm?? why not call it m/m?
