The Deluxe Edition is worth buying if you want the exclusive Dark Arts Pack cosmetics, the Thestral Mount, and 72 hours of early access. If those extras don’t matter to you, the Standard Edition gives you the exact same full game, story, and open world for $10–$20 less.

Formula

The calculator above works out your average running pace and speed from a finish time and distance. The formulas are:

Pace (min/km) = Finish time (minutes) ÷ Distance (km)

Speed (km/h) = Distance (km) ÷ (Finish time (minutes) ÷ 60)

Where:

  • t = finish time in minutes (e.g., 50 minutes)
  • d = distance in kilometers (e.g., 10 km)

Pace tells you how long it takes to cover one kilometer. Speed tells you how many kilometers you cover in one hour. Both are common ways to measure running performance, and you can convert between them with these two equations.

Worked Example

Using the default values from the calculator (t = 50 minutes, d = 10 km):

  1. Pace = 50 ÷ 10 = 5.00 min/km
  2. Speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h

So a 10 km run in 50 minutes means you average 5 minutes per kilometer, or 12 kilometers per hour. The calculator rounds both to two decimal places.

When to Use This Calculator

Use this tool whenever you have a finish time and distance and want to know your average pace or speed. Runners use pace to plan race splits, set training targets, and compare efforts across different distances. For example, if you ran a half marathon (21.1 km) in 1 hour 45 minutes, you’d enter 105 minutes and 21.1 km to get a pace of 4:59 per km. Coaches also use speed to prescribe interval workouts, like “run 400 m repeats at 12 km/h.”

The calculator works for any distance unit as long as you’re consistent. If you measure distance in miles, the pace output will be min/mile and speed will be mph. The math is the same; only the units change.

How to Read the Results

The first output, pace, is your headline result. A lower pace number means faster running. For example, 4:30 min/km is faster than 5:00 min/km. The second output, speed, is the inverse: a higher speed number means faster running. Most runners think in pace, while cyclists and treadmill users often think in speed.

If you want your pace in minutes per mile, just enter the distance in miles and the time in minutes. The result will be min/mile. To convert between min/km and min/mile, multiply or divide by 1.609. For instance, 5:00 min/km is roughly 8:03 min/mile.

Common Mistakes

  • Mixing units: Entering distance in miles but expecting min/km will give a wrong answer. Always use the same unit system for both inputs.
  • Forgetting to convert hours to minutes: If your time is 1:30:00, enter 90 minutes, not 1.5 or 1:30.
  • Rounding too early: If you round pace to 5.0 min/km and then compute speed, you’ll get 12.0 km/h, but the exact value is 12.0 only if the pace is exactly 5.0. The calculator handles this correctly by using the raw inputs.
  • Confusing pace and speed: A faster runner has a lower pace number but a higher speed number. They are reciprocals of each other.

Limitations of the Formula

This formula assumes a perfectly steady pace. In reality, your pace varies with terrain, elevation, wind, and fatigue. The result is an average, not a reflection of your instantaneous speed at any moment. It also doesn’t account for stops or walking breaks—if you paused your watch, the time you enter should be moving time, not elapsed time.

The formula works for any positive time and distance. There’s no upper limit on distance, but the calculator caps time at 100,000 minutes (about 69 days) to prevent accidental entries. The minimum for both is 0, which will produce a “Cannot compute” error since you can’t divide by zero.

Frequently Asked Questions

How do I convert min/km to min/mile?

Multiply the min/km value by 1.609 to get min/mile. For example, 5:00 min/km × 1.609 = 8:03 min/mile. To convert the other way, divide min/mile by 1.609.

What’s a good running pace for a beginner?

For a 10 km run, a beginner might average anywhere from 6:30 to 8:00 min/km (about 10:30 to 12:50 min/mile). That corresponds to speeds of 7.5 to 9.2 km/h. Fitness level, age, and training history all play a role, so focus on your own progress rather than comparing to others.

Does the calculator work for walking?

Yes. Enter the time and distance for any walk, and you’ll get your average walking pace and speed. Typical walking speed is 4.5 to 6.5 km/h (about 9 to 13 min/km).

Why does my GPS watch show a different pace?

GPS watches calculate pace in real-time using short intervals and often smooth the data. They may also include elevation gain or loss. Your average pace from a finish time and distance is the most accurate overall measure, but it won’t capture the variability within the run.

How do I calculate pace for a marathon (42.195 km)?

Enter 42.195 as the distance and your target finish time in minutes. For a 4-hour marathon, that’s 240 minutes. The calculator will give you a pace of 5:41 min/km (about 9:09 min/mile) and a speed of 10.55 km/h.

Can I use this for cycling or swimming?

Yes, the math is the same for any distance-based activity. For cycling, enter distance in miles or km and time in minutes to get mph or km/h. For swimming, enter distance in meters or yards—just remember the pace will be per meter/yard, which is less common but still valid.
