About Converting Centimeter per Minutes to Millimeter per Hours
Centimeter per Minutes and Millimeter per Hours 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 hours = centimeter per minutes × 600
This factor comes from each unit's defined relationship to the category's base unit: 1 centimeter per minutes equals 0.000166666666667 base units, and 1 millimeter per hours equals 2.777778e-7 base units, so dividing one by the other gives the direct centimeter per minutes-to-millimeter per hours factor of 600.
Simple example
1 cm/min × 600 = 600 mm/h
1 centimeter per minutes = 600 millimeter per hours.
Real-world example
10 cm/min × 600 = 6,000 mm/h
10 centimeter per minutes = 6,000 millimeter per hours.
