Pace Calculator

A Pace Calculator is an essential tool for runners, cyclists, and athletes (who may also benefit from our BMI Calculator) to determine their speed over a specific distance. By entering two of the three variables (Pace, Time, or Distance), the calculator instantly determines the missing value.

Example 1: Finding Your Pace

If you ran 5 miles in 45 minutes, entering those two values (Distance and Time) calculates your Pace automatically:

Example 2: Finding Your Finish Time

If you plan to run a 10K at a 9:00 min/km pace, entering those two values (Pace and Distance) calculates your expected finish Time:

How to use this calculator

1. Select the Tab for the value you want to calculate (Pace, Time, or Distance).
2. Enter the known variables. For example, if you want to know your Pace, enter your total Time and total Distance.
3. Choose your units. The calculator supports Miles, Kilometers, Meters, and Yards for distance, and various speeds including min/mi, mph, and km/h.
4. View Results instantly. The calculator will automatically compute the missing metric and display it in multiple unit conversions.

The Pace Formula

Pace is calculated with a simple relationship between time and distance:

Pace = Total Time ÷ Total Distance

For example, running 5 miles in 45 minutes gives 45 ÷ 5 = 9 minutes per mile. The same relationship rearranges to solve for either of the other two values, which is exactly what this calculator automates: Time = Pace × Distance, or Distance = Time ÷ Pace.

Understanding Pace Units

Min/Mile vs Min/Km

These are the two dominant pace units worldwide, and mixing them up is a common source of confusion for anyone comparing race results internationally. Min/mile is the standard in the US, while min/km is standard almost everywhere else, including most major international marathons. Because a mile is longer than a kilometer, a given running speed always produces a smaller min/km number than min/mile — for example, a 9:00 min/mile pace is roughly equivalent to a 5:35 min/km pace, so comparing raw numbers across the two units without converting will always be misleading.

MPH vs Km/H

These speed-based units (rather than pace-based) are more common on treadmills and for cycling than for outdoor running, since they express distance covered per hour rather than time needed per unit of distance. MPH is standard on US treadmills, while km/h is standard on most international ones — a 9:00 min/mile pace converts to roughly 6.7 mph, or about 10.7 km/h.

Pace Calculator vs Calories Burned Calculator: Planning a Run End to End

Pace and calories burned answer two different questions about the same run, which is why runners typically check both together when planning a race or training block. This Pace Calculator answers "how fast" — your speed, expected finish time, or target pace for a given distance. The Calories Burned Calculator answers "how much" — the energy cost of that same run, based on your body weight, the activity's MET value, and duration. Used together, they turn a single planned run into a complete picture: pace and finish time for the training or race plan itself, and calories burned for anyone also tracking that run against a daily calorie budget.
