FAQ
Questions Perceived Exertion Converter owners ask.
- 01
What is the Borg 6-20 scale?
The Borg 6-20 scale is a traditional method for measuring perceived physical exertion, where 6 represents no effort and 20 represents maximal intensity.
- 02
How accurate are the heart rate estimates?
The capability provides estimates based on the relative position of your RPE within the scale range applied to your maximum heart rate. It is a mathematical approximation for training guidance.
- 03
Can I use this without a heart rate monitor?
Yes, the primary purpose of these capabilities is to help you estimate intensity and training zones using only your subjective perception of effort.
