| Reference | knots | miles per hour |
|---|---|---|
| Brisk walk | 2.92 kn | 3.36 mph |
| Sprinting world record (avg) | 20.29 kn | 23.35 mph |
| City speed limit (50 km/h) | 27 kn | 31.07 mph |
| Highway cruising (100 km/h) | 54 kn | 62.14 mph |
| Commercial jet cruise | 486 kn | 559 mph |
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.
