About Converting Kilometer per Days to Nautical mile per Seconds
Kilometer per Days and Nautical mile 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
nautical mile per seconds = kilometer per days × 0.00000624950004
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 nautical mile per seconds equals 1852 base units, so dividing one by the other gives the direct kilometer per days-to-nautical mile per seconds factor of 0.00000624950004.
Simple example
1 km/d × 0.00000624950004 = 0.0000062495 nmi/s
1 kilometer per days = 0.0000062495 nautical mile per seconds.
Real-world example
10 km/d × 0.00000624950004 = 0.000062495 nmi/s
10 kilometer per days = 0.000062495 nautical mile per seconds.
