The Knots to Miles per Hour Converter converts speed from knots to miles per hour using the factor 1 knot = 1.15078 mph. This conversion is essential for aviation, maritime navigation, and weather reporting where knots are the standard speed unit.
A knot is defined as one nautical mile per hour, where 1 nautical mile = 1.852 km = 1.15078 statute miles. Knots are used internationally by pilots, sailors, and meteorologists because nautical miles correspond directly to minutes of latitude, simplifying navigation.
Understanding the knot-to-mph conversion is critical for pilots interpreting approach speeds, sailors comparing boat speeds to road speeds, and aviation enthusiasts following flight data.
Our converter also provides km/h for international reference.
The formula: mph = knots × 1.15078. Since 1 knot = 1 nautical mile/hour = 1.852 km/h, and 1 statute mile = 1.609344 km, we get 1 knot = 1.852/1.609344 = 1.15078 mph. For km/h: km/h = knots × 1.852 (exact).
Speed references: typical sailboat 5-8 knots (6-9 mph), cargo ship 12-16 knots (14-18 mph), cruise speed of Boeing 737 ~460 knots (529 mph), hurricane Category 1 ≥64 knots (74 mph).

1 knot = 1.15078 mph.
A knot is a unit of speed equal to 1 nautical mile per hour (1.852 km/h or 1.151 mph).
Knots are based on nautical miles, which correspond to minutes of latitude. This makes navigation calculations simpler.
100 mph = 86.90 knots.
Force 0 (calm) = 0-1 kn, Force 6 (strong breeze) = 22-27 kn, Force 12 (hurricane) = 64+ kn.
20 knots = 23.02 mph — a fast motorboat speed.
Mach 1 at sea level ≈ 661.5 knots (761.2 mph / 1234.8 km/h).
Multiply knots by 1.852. For example, 50 knots = 92.6 km/h.
A nautical mile = 1.852 km = 1.15078 statute miles = 1 minute of arc of latitude.
No, but it is accepted for use in maritime and aviation contexts. The SI unit of speed is m/s.
