Frequently Asked Questions
How do I calculate speed from distance and time?
Divide the distance by the time: speed = distance / time. For example, traveling 120 km in 2 hours gives a speed of 60 km/h.
How do I convert speed units?
To convert km/h to m/s, divide by 3.6. To convert mph to km/h, multiply by 1.609. To convert km/h to mph, divide by 1.609.
