About Converting Millimeter per Days to Meter per Hours
Millimeter per Days and Meter 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
meter per hours = millimeter per days × 0.0000416666666667
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 meter per hours equals 0.000277777777778 base units, so dividing one by the other gives the direct millimeter per days-to-meter per hours factor of 0.0000416666666667.
Simple example
1 mm/d × 0.00004166666667 = 0.0000416667 m/h
1 millimeter per days = 0.0000416667 meter per hours.
Real-world example
10 mm/d × 0.00004166666667 = 0.0004166667 m/h
10 millimeter per days = 0.0004166667 meter per hours.
