[–] LodeMike@lemmy.today 47 points 2 years ago (2 children) Just divide by 3.6 Example: 10 km /h * 1000 m / km = 10,000 m /h 10,000 m/h * 1h/3600s = 10,000/ 3,6000 m/s = 10/3.6 m/s permalink fedilink source hideshow 4 child comments replies: [–] Psythik@lemmy.world 25 points 2 years ago (2 children) Shit like this is why we need metric time. permalink fedilink source parent hideshow 4 child comments replies: [–] sparkle@lemm.ee 8 points 2 years ago don't speak like the french permalink fedilink source parent [–] the_crotch@sh.itjust.works 2 points 2 years ago (2 children) Shit like this is why metric needs to be replaced with a base12 system. Base10 is for children who still count on their fingers. permalink fedilink source parent hideshow 4 child comments replies: [–] BlueMagma@sh.itjust.works 2 points 2 years ago Dozenal for the win !!! It will never happen though, but dreaming is allowed permalink fedilink source parent [–] GoodEye8@lemm.ee 1 point 2 years ago If at could start at blank slate then base 12 would make a better foundation, but base 10 is far too ingrained into every aspect of our life. It's much easier to convert time into base 10 than it would be to convert the world into base 12. permalink fedilink source parent [–] MisterFrog@lemmy.world 2 points 2 years ago (1 child) I used to do it this way in highschool, but could never remember if it was divide by or multiply by 3.6 Instead I now do it as you have shown, except it all goes in the same expression. 10 km/h * 1000 m/km * 1h/3600s = 2.778 m/s No need for the extra steps. Slap it all in the same expression and put it in the calculator (being careful to check that the units cancel as intended) permalink fedilink source parent hideshow 2 child comments replies: [–] fushuan@lemm.ee 1 point 2 years ago (1 child) M/s is faster (lower number) than km/h so... That should give you enough explanation to understand whether you need to divide or multiply 3.6 when converting. permalink fedilink source parent hideshow 2 child comments replies: [–] MisterFrog@lemmy.world 1 point 2 years ago It just never stuck. Just for me personally it's easier to remember the base conversions of 1 km = 1000 m and 1 hr = 3600 and do the maths. Just my own personal preference, and when dealing with more complex units, is the only way. permalink fedilink source parent
