minus-squarebleistift2@feddit.delinkfedilinkEnglisharrow-up2·6 months agoWhy km/h (or mph) and not ft/year? Because the numbers have a nicer magnitude then.
minus-squarenooneescapesthelaw@mander.xyzlinkfedilinkEnglisharrow-up7arrow-down1·6 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
