Speed Calculator — Frequently Asked Questions
Q1 What is the formula for calculating speed, distance, and time? ▾
Speed = Distance / Time; Distance = Speed × Time; Time = Distance / Speed.
Q2 What is the difference between average speed and instantaneous speed? ▾
Average speed is total distance divided by total elapsed time. Instantaneous speed is the velocity at an exact moment in time, as indicated by a vehicle speedometer.
Q3 How do you convert miles per hour (mph) to kilometers per hour (km/h)? ▾
Multiply mph by 1.60934 to get km/h (or divide km/h by 1.60934 to get mph). 1 meter per second (m/s) equals 2.237 mph or 3.6 km/h.
Q4 How is running pace calculated from speed? ▾
Pace is the inverse of speed (Time / Distance), expressed as minutes per mile or minutes per kilometer. For example, 6.0 mph equals a 10:00 min/mile pace.
