About Converting Meter per Days to Nautical mile per Seconds
Meter 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 = meter per days × 6.2495e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 meter per days equals 0.0000115740740741 base units, and 1 nautical mile per seconds equals 1852 base units, so dividing one by the other gives the direct meter per days-to-nautical mile per seconds factor of 6.2495e-9.
Simple example
1 m/d × 6.2495e-9 = 6.2495e-9 nmi/s
1 meter per days = 6.2495e-9 nautical mile per seconds.
Real-world example
10 m/d × 6.2495e-9 = 6.2495e-8 nmi/s
10 meter per days = 6.2495e-8 nautical mile per seconds.
