About Converting m/s to Nautical mile per Days
m/s and Nautical mile 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). m/s is most often used for scientific and engineering speed/velocity calculations.
Formula
nautical mile per days = m/s × 46.6522678186
This factor comes from each unit's defined relationship to the category's base unit: 1 m/s equals 1 base unit, and 1 nautical mile per days equals 0.0214351851852 base units, so dividing one by the other gives the direct m/s-to-nautical mile per days factor of 46.6522678186.
Simple example
1 m/s × 46.65226782 = 46.65226782 nmi/d
1 m/s = 46.65226782 nautical mile per days.
Real-world example
10 m/s × 46.65226782 = 466.5226782 nmi/d
10 m/s = 466.5226782 nautical mile per days.

Understanding the m/s
m/s (m/s) measures speed. The meter per second is the SI derived unit of speed: one meter of distance per second of time. It is classified as a SI derived unit.
Where it's used: Standard scientific speed unit worldwide
Uses of the m/s today
- Scientific and engineering speed/velocity calculations
- Meteorology (wind speed, alongside km/h and knots)
- Physics education and calculations
History of the m/s
As a coherent SI derived unit, meters per second follows automatically from the meter and second, the SI base units of length and time, without an independent historical origin.
Historical origin. m/s was not the invention of a single named person; it developed through the process described above.
