What's the ratio between a single turn (base 100 moves) and a single mph?

Overall, it’s not too big of a deal, but I’d like to know just how much faster I’m going at a low speed like 4 mph.

Average walking speed looks to be approx 4mph, so at 4 mph it’s about 1 tile per turn.

(Just Debug tested, that’s what it seems, please correct me if I’m wrong)

Okay, good to know. Thanks.

You can also change the vehicle speed to be in tiles/turn.
This shows vehicle movement per 100 moves.

Really? I assume that’s in the setting somewhere. I’ll look for that.
