Frequently Asked Questions
How do I convert mph to knots?
Divide by 1.15078. For example, 100 mph ÷ 1.15078 ≈ 86.9 knots.
How many knots is 60 mph?
About 52.1 knots. A rough mental rule: knots are roughly 87% of the mph figure.
Is a knot faster than a mile per hour?
Yes, slightly. One knot is 1.15 mph, because a nautical mile (1,852 m) is longer than a statute mile (1,609 m). Saying "knots per hour" is a common error — the "per hour" is already inside the word.
What speed do aircraft cruise at in knots?
A typical airliner cruises around 450–500 knots of true airspeed, which is roughly 520–575 mph. Small propeller aircraft cruise nearer 100–150 knots.
