About Converting Centimeter per Days to Millimeter per Seconds
Centimeter per Days and Millimeter 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
millimeter per seconds = centimeter per days × 0.000115740740741
This factor comes from each unit's defined relationship to the category's base unit: 1 centimeter per days equals 1.157407e-7 base units, and 1 millimeter per seconds equals 0.001 base units, so dividing one by the other gives the direct centimeter per days-to-millimeter per seconds factor of 0.000115740740741.
Simple example
1 cm/d × 0.0001157407407 = 0.0001157407 mm/s
1 centimeter per days = 0.0001157407 millimeter per seconds.
Real-world example
10 cm/d × 0.0001157407407 = 0.0011574074 mm/s
10 centimeter per days = 0.0011574074 millimeter per seconds.
