How to convert knots to miles per hour
Knots and miles per hour both measure speed as distance per hour, but use different distance units. One knot (nautical mile per hour) equals 1.15078 statute miles per hour. This difference matters in aviation and marine contexts.
Multiply knots by 1.15078 to get mph. Formula: mph = kn × 1.15078. 10 knots = 11.51 mph. 30 knots (strong wind) = 34.52 mph. A 500-knot jet (hypothetically) = 575 mph.
US weather reports sometimes give wind in mph while aviation uses knots. Boat speedometers may show knots; recreational boaters often think in mph.
Quick values: 1 kn ≈ 1.15 mph, 10 kn ≈ 11.5 mph, 50 kn ≈ 57.5 mph. 1 mph = 0.868976 knots.
