About Converting Millimeter per Hours to Centimeter per Minutes
Millimeter per Hours and Centimeter per Minutes both describe speed, and the conversion matters whenever a maritime or aviation speed (knots) needs to be compared against a road speed (mph). Both are distance divided by time units.
Formula
centimeter per minutes = millimeter per hours × 0.00166666666667
This factor comes from each unit's defined relationship to the category's base unit: 1 millimeter per hours equals 2.777778e-7 base units, and 1 centimeter per minutes equals 0.000166666666667 base units, so dividing one by the other gives the direct millimeter per hours-to-centimeter per minutes factor of 0.00166666666667.
Simple example
1 mm/h × 0.001666666667 = 0.0016666667 cm/min
1 millimeter per hours = 0.0016666667 centimeter per minutes.
Real-world example
10 mm/h × 0.001666666667 = 0.0166666667 cm/min
10 millimeter per hours = 0.0166666667 centimeter per minutes.
