1 m/s = 1/1000 km / 1/3600 h = 1/1000 km *3600 /1 h = 3,6 km/h więc: 1 m/s = 3,6 km/h 15 m/s = 15 *3,6 km/h = 54 km/h   15 km/h = 15 *1000 m/3600 s ≈ 4,17 km/h   54 km/h = 54*1000 m /3600 s = 15 m/s 108 km/h = 108 * 1000 m/3600 s = 30 m/s   1 m/s = 3,6 km/h 36 m/s = 36 * 3,6 km/h = 129,6 km/h   1 m/s = 3,6 km/h 5 m/s = 5 *3,6 km/h = 18 km/h
