Calculate speed, distance or time using the formula v = s ÷ t. Fill in two of the three fields and leave the third at 0, and the calculator works out the rest.
Speed (v) is the distance (s) you travel divided by the time (t) it takes. In physics, speed is normally given in meters per second (m/s), but in everyday life we're more used to kilometers per hour (km/h). Remember that 1 m/s = 3.6 km/h — the calculator therefore always shows the result in km/h too, as extra context.
If you know two of the three values, you can solve the equation for the third: s = v × t to find distance, or t = s ÷ v to find time.
Multiply the speed in m/s by 3.6 to get km/h. For example, 10 m/s equals a speed of 36 km/h. The calculator above does this conversion automatically.
Speed is how much distance is covered per unit of time, and has no direction (a scalar quantity). Velocity also includes direction (a vector quantity). In everyday language we often use the words interchangeably, but in physics the distinction matters.
Yes, but remember that running pace (min/km) is the inverse of speed. Calculate your speed in m/s or km/h here, then convert it to minutes per kilometer if that's what you need.
