Yes. Or go with 25mm/s in that case, but because metric is trivial to move up/down to different sized units that is simple to do.

Meanwhile in imperial, fuck knows. 12 inches to a foot, 3 feet to a yard and then some number over 1000 yards to a mile.

Even worse with volume, which fucking gallon are you using? There are different ones! It might be (vaguely close to) 3.5L, or 4.5L! I think there might even be another one somewhere.
