About Converting Millimeter per Hours to Centimeter per Hours
Millimeter per Hours and Centimeter 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
centimeter per hours = millimeter per hours × 0.1
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 hours equals 0.00000277777777778 base units, so dividing one by the other gives the direct millimeter per hours-to-centimeter per hours factor of 0.1.
Simple example
1 mm/h × 0.1 = 0.1 cm/h
1 millimeter per hours = 0.1 centimeter per hours.
Real-world example
10 mm/h × 0.1 = 1 cm/h
10 millimeter per hours = 1 centimeter per hours.
Conversion table
| Millimeter per Hours (mm/h) | Centimeter per Hours (cm/h) |

| 5 mm/h | 0.5 cm/h |
| 10 mm/h | 1 cm/h |
| 25 mm/h | 2.5 cm/h |
| 50 mm/h | 5 cm/h |
| 100 mm/h | 10 cm/h |
Reverse conversion: Centimeter per Hours to Millimeter per Hours
0.1 cm/h × 10 = 1 mm/h
0.1 centimeter per hours = 1 millimeter per hours.
millimeter per hours = centimeter per hours × 10
