Treadmills are popular exercise machines. Many people use them to walk, jog, or run inside. When you look at a treadmill, you may see the speed shown in miles per hour (mph). But are all treadmills in mph? The short answer is no. Some treadmills show speed in kilometers per hour (km/h).
What Does Mph Mean?
Mph stands for miles per hour. It tells how many miles you travel in one hour. For example, if you run at 5 mph, you move 5 miles in one hour. Mph is common in countries like the United States and the United Kingdom.
What Is Km/h?
Km/h means kilometers per hour. It shows how many kilometers you travel in one hour. For example, 8 km/h means you move 8 kilometers in one hour. Km/h is used in many countries around the world, like most of Europe and Canada.
Why Do Treadmills Use Different Units?
Treadmills show speed in different units because of where they are sold. In the U.S., mph is common. In other countries, like Germany or Japan, km/h is standard. Manufacturers make treadmills for different markets. So, they use the unit people know best.

Can You Change The Unit On A Treadmill?
Some treadmills let you switch between mph and km/h. This is helpful if you move to a new country or like to use different units. Usually, you can change the unit in the settings or menu on the treadmill screen. But not all treadmills have this option.
How To Know If Your Treadmill Uses Mph Or Km/h?
- Look at the speed display on the treadmill screen.
- Check the user manual. It will say which unit is used.
- Look for a settings button to change units.
- Ask the seller or check the product description online.
Why Does Unit Matter?
The unit matters because it changes how you understand speed. If you want to run 6 miles per hour, but the treadmill shows 6 km/h, you will run slower. This can affect your workout goals. It is important to know which unit your treadmill uses.
Speed Conversion Between Mph And Km/h
If you see the speed in km/h but want mph, you can convert it. Here is a simple way:
| Unit | Conversion | Example |
|---|---|---|
| 1 mph to km/h | Multiply by 1.609 | 1 mph = 1.609 km/h |
| 1 km/h to mph | Divide by 1.609 | 1 km/h ≈ 0.62 mph |
So, if a treadmill shows 10 km/h, that equals about 6.2 mph. Knowing this helps you set the right speed.
Do All Treadmills Show Speed?
Most treadmills show speed. But some basic or manual models do not. Instead, they may show time, distance, or calories burned. If speed is important to you, check if the treadmill shows it and which unit it uses.

No, not all treadmills use miles per hour (mph). Some models use kilometers per hour (km/h) depending on the region.
Can I Change Treadmill Speed From Mph To Km/h?
Yes, most treadmills allow you to switch between mph and km/h in the settings menu. Check your user manual for instructions.
Do Treadmills In Europe Usually Show Speed In Mph?
Treadmills in Europe often display speed in kilometers per hour (km/h) instead of mph. This matches local measurement standards.
Why Do Some Treadmills Only Show Speed In Km/h?
Treadmills sold outside the US mostly use km/h because it is the standard unit in many countries. It suits local users better.
Conclusion
Not all treadmills use mph. Some use km/h. It depends on the country and the treadmill model. You can often change the unit in settings. Knowing the unit helps you track your speed and workout better. Always check your treadmill before use. This way, your exercise will be safe and effective.
