Calculate speed, distance, and time instantly. Free online speed calculator with pace conversion for running, cycling, and driving.
The speed calculator computes speed and pace from distance and time inputs. Speed is the rate at which an object covers distance, while pace is the inverse — the time it takes to cover a unit of distance. Both are essential metrics for athletes, drivers, and travelers.
Speed = Distance ÷ Time | Pace = Time ÷ DistanceSpeed is calculated by dividing distance by time. Pace is the inverse of speed — it tells you how long it takes to cover one unit of distance. For runners, pace is typically expressed as minutes per kilometer or mile.
