Instructions
On this page, you'll find instructions on how to calculate the real speed of your treadmill, and instructions for calibration. I also wrote a manual detailing every step. Download it for free (coming soon(ish)). You can also calculate speeds between two known, calibrated speeds. For instance, when you calculated the true speed of your treadmill at 10 and 16 kph, you can calculate the speeds at 11, 12, 13, 14 and 15 kph. Mind that linear interpolation is used for this, which assumes the deviation of your treadmill is constant.
Please note that you can, but don't have to calibrate your treadmill. Treadmills tend to run a little bit slower than the speeds their displays present, but other measures, such as GPS in watches, aren't perfect either. It really is up to you.
alculate your real treadmill speed on this page. Please first take the following steps, and then enter the acquired values into the form below.
Steps for treadmill calibration
- Measure belt length in centimeters.
- Set the treadmill at a certain speed, such as 6 kph.
- Count the rotations for (exaclty) one minute.
- Fill in the measurements and click the button.
Steps for speed interpolation
- Calculate the calibrated speed of your treadmill at low and high speed (e.g, 6 and 16 kph).
- Enter the two treadmill speeds and the two calibrated speeds and click the button.
Calibrate
Enter your measurements here when you have collected them, and after hitting the button, check the calibrated speed.

If you cannot calibrate your treadmill or speed sensor, or you do not have one, you can set your treadmill to ... kph to run at ... kph in reality.
Interpolate
Enter your calibrated measurements for low and high speed and calculate the speeds in between.
