Speed & Velocity Converter
Speed represents the rate of distance covered per unit of time. Convert between vehicular speeds (mph and km/h), nautical velocities (knots), and physics standards (m/s).
Common Speed & Velocity Converter Conversions
| Unit Standard | Target Equivalent | Formula | Practical Example |
|---|---|---|---|
| 60 Miles per Hour | 96.56 Km/h | mph × 1.609344 = km/h | 60 mph = 96.56 km/h |
| 100 Kilometers per Hour | 62.14 Mph | km/h ÷ 1.609344 = mph | 100 km/h = 62.14 mph |
| 1 Knot | 1.15078 Mph | kn × 1.15078 = mph | 20 kn = 23.02 mph |
How Speed & Velocity Converter Math Works
Speed conversions multiply distance ratios by time inverse ratios. 1 mph equals exactly 1.609344 km/h (0.44704 m/s). 1 knot equals 1.852 km/h.
