How to convert miles per hour to knots
Worked example: 60 mph ≈ 52.14 knots
60 mph × 1,609.344 ÷ 1,852 ≈ 52.14 knots
1,852 m in a nautical mile; 1,609.344 m in a mile
Rule: knots = miles per hour × 1,609.344 ÷ 1,852 ≈ miles per hour ÷ 1.15078 — 1 kt = 1 nautical mile per hour = 1,852 m/h; 1 mph = 1,609.344 m/h.

FAQ
How many knots is a mile per hour?
1 mph ≈ 0.868976 knots: knots = mph × 1,609.344 ÷ 1,852 ≈ mph ÷ 1.15078. For most inputs the division does not end, and the answer is rounded: 60 mph ≈ 52.14 knots; it comes out exact only for uncommon inputs such as 144.6875 mph = 125.73 knots.
Where do 1,609.344 and 1,852 come from?
A mile per hour is one statute mile per hour, and a knot is one nautical mile per hour. By the international definitions, 1 mile = 1,609.344 m (1959) and 1 nautical mile = 1,852 m (1929), so 1 mph = 1,609.344 m/h and 1 knot = 1,852 m/h.
Why is the number in knots smaller than in mph?
A nautical mile is longer than a statute mile: 1 nautical mile ≈ 1.15078 mi. So the same speed is a smaller number in knots: 100 mph ≈ 86.9 knots, and 1 knot ≈ 1.15078 mph.
Is a knot a distance?
No. A knot is a speed: one nautical mile per hour. The distance is the nautical mile.
