How this pace calculator works
This calculator converts your total time and distance into average pace per kilometer and per mile.
It also converts the result into average speed, which can be helpful for running, walking, cycling, treadmill pacing, and training plans.
Formula
Pace formula
Pace = Total time ÷ Distance
Speed formula
Speed = Distance ÷ Time
What is a pace calculator?
A pace calculator helps you calculate running pace, walking pace, average speed, and split pace based on distance and total time. It is useful for runners, walkers, treadmill users, race training, and anyone who wants a quick way to convert time and distance into a practical pace.
Many people search for a running pace calculator or walking pace calculator when preparing for a 5K, 10K, half marathon, marathon, treadmill session, or general fitness routine. By entering your distance and finish time, you can quickly find pace per kilometer, pace per mile, speed in km/h, and speed in mph.
How to calculate running pace
Running pace is calculated by dividing your total time by the total distance covered. For example, if you run 5 kilometers in 25 minutes, your average pace is 5:00 per kilometer.
The same idea works for miles. If you complete 3.1 miles in about 25 minutes, your pace is a little over 8 minutes per mile. This is why a pace calculator is helpful: it lets you switch between pace per kilometer, pace per mile, and speed without doing the conversions by hand.

Common uses for a running or walking pace calculator
A pace calculator is useful for race planning, treadmill workouts, interval sessions, walking programs, and personal training goals. It helps you estimate whether your current pace matches your target for events like a 5K, 10K, half marathon, or marathon.
It is also useful after a workout. If you know the time and distance, you can quickly work out whether you maintained a steady pace, improved your speed, or need to adjust future training.
Pace per mile vs pace per kilometer
Pace per mile and pace per kilometer measure the same idea, but the unit is different. Because a mile is longer than a kilometer, pace per mile will always show a larger time number than pace per kilometer for the same effort.
Some runners prefer pace per mile because many race events and treadmill displays use miles. Others prefer pace per kilometer because it is common in international training plans and shorter split tracking. A good pace calculator gives you both instantly.
Example pace calculations
Example: 5K pace
If you complete 5 kilometers in 25 minutes, your pace is about 5:00 per kilometer and about 8:03 per mile.
Example: walking pace
If you walk 3 miles in 45 minutes, your average pace is 15:00 per mile, which is about 9:19 per kilometer.
Pace calculator FAQ: running pace, walking pace, speed, and splits
What is the difference between pace and speed?
Pace is the time needed to cover one unit of distance, such as minutes per kilometer or minutes per mile. Speed is the distance covered in a unit of time, such as kilometers per hour or miles per hour.
How do I calculate running pace?
Running pace is calculated by dividing your total time by your total distance. A pace calculator does this automatically and can also show pace per mile, pace per kilometer, and average speed.
Can I use this for walking and running?
Yes. This calculator works for walking, running, treadmill sessions, jogging, and other pace-based activities.
Can this calculator show pace per mile and pace per kilometer?
Yes. It converts your result into both pace per mile and pace per kilometer so you can compare training data in either unit.
What is a good running pace?
A good running pace depends on your fitness level, training history, terrain, age, and race goals. Beginners usually run at a slower pace than trained runners, and the best pace is the one that matches your current ability and target event.
Can I use this pace calculator for treadmill workouts?
Yes. A treadmill pace calculator can help you understand how your treadmill speed translates into pace per mile or pace per kilometer.
Why is pace per mile different from pace per kilometer?
A mile is longer than a kilometer, so pace per mile will always take more time than pace per kilometer for the same effort.
