What does this speed converter convert?
Speed is distance over time. Different fields use very different units — road traffic (km/h or mph), athletics (m/s), aviation/sailing (knots), physics (m/s).
How conversion works
All units convert via meters per second. 1 km/h ≈ 0.278 m/s, 1 mph = 1.609 km/h, 1 knot = 1.852 km/h.
