What is 1 mile per hour in knots?

0.87 Knot 1.15 Knot 1.00 Knot 2.00 Knot

Correct Answer:

0.87 Knot

Explanation:

Knots are nautical miles per hour, while miles per hour use statute miles. Since 1 nautical mile is about 1.15078 statute miles, 1 statute mile is 1/1.15078 ≈ 0.868976 nautical miles. So 1 mile per hour equals about 0.868976 nautical miles per hour, i.e., roughly 0.87 knots. A handy way to remember this is that 1 knot is about 1.15 mph, so converting mph to knots is roughly dividing by 1.15 or multiplying by 0.87. Therefore, 1 mph equals about 0.87 knots.
