What is a knot?
A knot (kn) is one nautical mile per hour (1.852 km/h), used at sea and in aviation.
What is a kilometers per hour?
Kilometers per hour (km/h) is the metric speed unit for vehicles.
Real-world reference points
Walking is ~5 km/h (3 mph); city driving ~50 km/h (31 mph); a jet cruises near 900 km/h (560 mph).
| Reference | knots | kilometers per hour |
|---|---|---|
| Brisk walk | 2.92 kn | 5.4 km/h |
| Sprinting world record (avg) | 20.29 kn | 37.58 km/h |
| City speed limit (50 km/h) | 27 kn | 50 km/h |
| Highway cruising (100 km/h) | 54 kn | 100 km/h |
| Commercial jet cruise | 486 kn | 900 km/h |
Mistakes to avoid with speed conversions
- Dividing instead of multiplying by 3.6 when moving between m/s and km/h.
- Assuming knots equal mph — a knot is ~15% faster (nautical miles per hour).
- Comparing GPS speed (ground speed) with a car's speedometer, which reads slightly high by design.
