Speed/pace/distance/time converter.. Pace Calculator is a free online tool from the ToolsRift Finance & Health Calculators collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Enter any two of pace, speed, distance or time. The calculator solves for the remaining value and lets you switch between metric and imperial units.
Pace = time / distance, usually expressed as minutes per kilometre or mile. Running 10 km in 50 minutes is a pace of 5 minutes per kilometre.
Pace is time per unit distance (min/km), while speed is distance per unit time (km/h). Both describe the same effort from opposite angles.
Enter your target pace and the race distance, and the calculator multiplies them to project your total finish time for the event.
