I’m honestly surprised you’ve never had to do that, because it happens to me all the time.
Like when I’m approaching a junction on the road and the satnav suddenly changes from saying 0.5 miles to like 500 yards, that’s jarring and breaks my mental countdown. (In Britain, the roads are imperial, yes it’s a pain.)
Or if I’m cooking an old recipe and it needs 12oz of something, but I’m doubling the quantity, suddenly I need to know what that is in lb and oz because my scale doesn’t just tell me 24oz.
Or if someone says they’re 5’ 8" tall, I have to know how many " in a ’ to conceptualise how close that is to 6’.
Meanwhile, I know when I’m out hiking what my pacing is for 100m, and if I’ve got 2.5km to go, that’s 25 lots of pacing.
Or when I’m sewing, and fabric is sold by the metre but all the pattern pieces are measured in cm or mm.
And not strictly related, but it’s handy being able to measure out water in an unmarked container using a weighing scale and the fact that 1l=1kg.


I’ve been the car driver who nearly made jam out of the cyclist in the last panel. I’ve also been the cyclist hit by a car which was driving in the cycle lane.
Bad road users are everywhere and they use all sorts of transportation. Let’s stop with the division and generalisation.
