About Converting Millimeter per Seconds to Centimeter per Days
Millimeter per Seconds 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 seconds × 8640
This factor comes from each unit's defined relationship to the category's base unit: 1 millimeter per seconds equals 0.001 base units, and 1 centimeter per days equals 1.157407e-7 base units, so dividing one by the other gives the direct millimeter per seconds-to-centimeter per days factor of 8640.
Simple example
1 mm/s × 8640 = 8,640 cm/d
1 millimeter per seconds = 8,640 centimeter per days.
Real-world example
10 mm/s × 8640 = 86,400 cm/d
10 millimeter per seconds = 86,400 centimeter per days.
