About Converting Centimeter per Seconds to Millimeter per Days
Centimeter per Seconds and Millimeter 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
millimeter per days = centimeter per seconds × 864000
This factor comes from each unit's defined relationship to the category's base unit: 1 centimeter per seconds equals 0.01 base units, and 1 millimeter per days equals 1.157407e-8 base units, so dividing one by the other gives the direct centimeter per seconds-to-millimeter per days factor of 864000.
Simple example
1 cm/s × 864000 = 864,000 mm/d
1 centimeter per seconds = 864,000 millimeter per days.
Real-world example
10 cm/s × 864000 = 8,640,000 mm/d
10 centimeter per seconds = 8,640,000 millimeter per days.
