Speed Calculator

Calculate average speed from distance and time with v = d / t, with the result in m/s and km/h and a worked sprint example.

Calculator

Speed (m/s)10.4384 m/s
Speed (km/h)37.5783 km/h

Method, variables and units

Speed Calculator

Formula: v = d / t

  • v — speed (m/s)
  • d — distance (m)
  • t — time (s)

Assumption: Distance and time describe the same interval, and time is greater than zero.

Worked example

Speed Calculator

100 m in 9.58 s is 10.44 m/s, or 37.46 km/h.
