About Converting Millimeter per Hours to Nautical mile per Seconds
Millimeter per Hours 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 = millimeter per hours × 1.49988e-10
This factor comes from each unit's defined relationship to the category's base unit: 1 millimeter per hours equals 2.777778e-7 base units, and 1 nautical mile per seconds equals 1852 base units, so dividing one by the other gives the direct millimeter per hours-to-nautical mile per seconds factor of 1.49988e-10.
Simple example
1 mm/h × 1.49988e-10 = 1.49988e-10 nmi/s
1 millimeter per hours = 1.49988e-10 nautical mile per seconds.
Real-world example
10 mm/h × 1.49988e-10 = 1.49988e-9 nmi/s
10 millimeter per hours = 1.49988e-9 nautical mile per seconds.
