About Converting Kilometer per Days to Kilometer per Seconds
Kilometer per Days and Kilometer 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
kilometer per seconds = kilometer per days × 0.0000115740740741
This factor comes from each unit's defined relationship to the category's base unit: 1 kilometer per days equals 0.0115740740741 base units, and 1 kilometer per seconds equals 1000 base units, so dividing one by the other gives the direct kilometer per days-to-kilometer per seconds factor of 0.0000115740740741.
Simple example
1 km/d × 0.00001157407407 = 0.0000115741 km/s
1 kilometer per days = 0.0000115741 kilometer per seconds.
Real-world example
10 km/d × 0.00001157407407 = 0.0001157407 km/s
10 kilometer per days = 0.0001157407 kilometer per seconds.
