419 mm/900 ms x 1km/10^6 mm x 3.6x10^6 ms/h = 1.676 km/h.

In general, compound conversions are easily handled by cascading the two separate conversions, km to mm, and hour to second, in a "chain rule" and multiplying out.

Re: converting mm/ms to km/h
What is 1km/h to m/s or 1m/s to km/h

Re: converting mm/ms to km/h
1 m/s x 3600 s/1 h x 1 km/1000 m = 3.6 km/h

Re: converting mm/ms to km/h
Hi,
My problem is reverse : how do I get 320 km/h to mm/ms ? I have ESBUnitConv, but they do not list milliseconds. Thanks a lot.

Recognize that an hour is 3.6 ks (3600 s) 320 km/h x 1 h/3.6 ks = 88.9 m/s = 88.9 mm/ms You get an endless repeating decimal, but you have to ask what is the practical accuracy of the 320 km/h datapoint and decide where to cut it off to avoid "decimal dust."
