2200 would improperly add an extra significant figure, "about 2000" would be okay.

I had figured since km/h was NN00, the same would be good for mph.

Naw, it's already been false precisioned to hell.

The original would have been "about 1000 metres/second". That got translated to 3600 km/h etc.

Check how much it charges if it was really 800 m/s. Or 1200 m/s.
