GPS speedometer
See your current speed while walking, running, cycling, or travelling. Choose your units and follow live speed, distance, and course on one clear display.
Ready when you are. Allow location to measure your speed.
Mach uses 343 m/s, approximately the speed of sound in dry air at 20°C. Actual sound speed varies with conditions.

Allow location access to receive live device readings. When the device reports speed, it is used directly. Otherwise, successive accurate positions provide a distance-over-time estimate. An approximate network location cannot measure speed.
Accuracy depends on the device and signal. Buildings, tunnels, and weak reception can interrupt readings. Position estimates filter small GPS drift; very slow movement may take longer to detect. Old readings are cleared instead of appearing live.
After an online visit, this page and its essential files are saved when browser caching is available. GPS can keep working offline if the device provides fixes. Keep the page open; background updates vary by browser.
Choose mph, km/h, knots, m/s, ft/s, cm/s, or approximate Mach. Running pace shows minutes per kilometre or mile; a lower pace means faster movement. At rest, pace has no finite value.
