About Converting Millimeter per Days to Centimeter per Seconds
Millimeter per Days and Centimeter per Seconds 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 seconds = millimeter per days × 0.00000115740740741
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 seconds equals 0.01 base units, so dividing one by the other gives the direct millimeter per days-to-centimeter per seconds factor of 0.00000115740740741.
Simple example
1 mm/d × 0.000001157407407 = 0.0000011574 cm/s
1 millimeter per days = 0.0000011574 centimeter per seconds.
Real-world example
10 mm/d × 0.000001157407407 = 0.0000115741 cm/s
10 millimeter per days = 0.0000115741 centimeter per seconds.
