About Converting Millimeter per Days to Centimeter per Days
Millimeter per Days and Centimeter per Days 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 days = millimeter per days × 0.1
This factor comes from each unit's defined relationship to the category's base unit: 1 millimeter per days equals 1.157407e-8 base units, and 1 centimeter per days equals 1.157407e-7 base units, so dividing one by the other gives the direct millimeter per days-to-centimeter per days factor of 0.1.
Simple example
1 mm/d × 0.1 = 0.1 cm/d
1 millimeter per days = 0.1 centimeter per days.
Real-world example
10 mm/d × 0.1 = 1 cm/d
10 millimeter per days = 1 centimeter per days.
Conversion table
| Millimeter per Days (mm/d) | Centimeter per Days (cm/d) |
|---|---|
| 1 mm/d | 0.1 cm/d |
| 5 mm/d | 0.5 cm/d |
| 10 mm/d | 1 cm/d |
| 25 mm/d | 2.5 cm/d |
| 50 mm/d | 5 cm/d |
| 100 mm/d | 10 cm/d |
Reverse conversion: Centimeter per Days to Millimeter per Days
0.1 cm/d × 10 = 1 mm/d
0.1 centimeter per days = 1 millimeter per days.
millimeter per days = centimeter per days × 10
