1 knot = 1.852 km/h · 1 knot = 1.15078 mph

How to convert knots to km/h

To convert knots to kilometers per hour, multiply by 1.852. For example, 100 knots × 1.852 = 185.2 km/h. Going the other way, divide km/h by 1.852 to get knots.

To convert knots to mph, multiply by 1.15078. So 100 knots × 1.15078 = 115.078 mph.

1 knot = 1 nautical mile per hour = 1.852 km/h = 1.15078 mph. Knots are used in aviation and maritime navigation. The conversion factor of 1.852 is exact by definition.
