About Converting Kilometer per Seconds to Centimeter per Days
Kilometer 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 = kilometer per seconds × 8640000000
This factor comes from each unit's defined relationship to the category's base unit: 1 kilometer per seconds equals 1000 base units, and 1 centimeter per days equals 1.157407e-7 base units, so dividing one by the other gives the direct kilometer per seconds-to-centimeter per days factor of 8640000000.
Simple example
1 km/s × 8640000000 = 8,640,000,000 cm/d
1 kilometer per seconds = 8,640,000,000 centimeter per days.
Real-world example
10 km/s × 8640000000 = 86,400,000,000 cm/d
10 kilometer per seconds = 86,400,000,000 centimeter per days.

Reverse conversion: Centimeter per Days to Kilometer per Seconds
1 cm/d × 1.157407e-10 = 1.157407e-10 km/s
1 centimeter per days = 1.157407e-10 kilometer per seconds.
kilometer per seconds = centimeter per days × 1.157407e-10
