What this conversion means in practice
Knots tie cleanly to nautical miles (1852 m); mph uses statute miles (1609.344 m). Mixing them without converting is a classic briefing error when comparing aircraft or ship speeds to road intuition.
The exact relationship here is 1 kn = 1.150779448024 mph, consistent with expressing both units relative to meters per second (m/s).
How to convert knot to mile per hour
Multiply the knot value by 1.150779448024 to get mile per hour.
Example: 1 kn × 1.150779448024 = 1.150779448024 mph.
