About Converting Centimeter per Hours to Millimeter per Minutes
Centimeter per Hours and Millimeter 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
millimeter per minutes = centimeter per hours × 0.166666666667
This factor comes from each unit's defined relationship to the category's base unit: 1 centimeter per hours equals 0.00000277777777778 base units, and 1 millimeter per minutes equals 0.0000166666666667 base units, so dividing one by the other gives the direct centimeter per hours-to-millimeter per minutes factor of 0.166666666667.
Simple example
1 cm/h × 0.1666666667 = 0.1666666667 mm/min
1 centimeter per hours = 0.1666666667 millimeter per minutes.
Real-world example
10 cm/h × 0.1666666667 = 1.666666667 mm/min
10 centimeter per hours = 1.666666667 millimeter per minutes.
