1 ft/s = 1.09728 km/h

Example: 1 foot per second = 1.09728 kilometer per hour

A knot is one nautical mile per hour, exactly 1.852 km/h, not 1 km/h. A boat doing 20 knots travels at about 37 km/h. Multiply knots by 1.852 to get km/h.
Between m/s and km/h the factor is 3.6, an hour has 3,600 seconds and a kilometer 1,000 meters. Multiply m/s by 3.6 to get km/h (10 m/s = 36 km/h) and divide going the other way. Flipping the factor produces a thirteen-fold error.
UK and US road signs show miles per hour, not km/h. 1 mph is about 1.609 km/h, so a '70' limit means about 113 km/h. Multiply mph by 1.6 to think in km/h.
