The Perceived Exertion Converter bridges the gap between subjective effort and objective physiological metrics. Using the convert_borg_6_20_scale and convert_cr10_scale tools, athletes can translate their Rate of Perceived Exertion (RPE) into estimated heart rate, percentage of maximum capacity, and specific training zones like Aerobic or Threshold. This is ideal for training without a continuous heart rate monitor. Additionally, use get_training_guidance to receive qualitative intensity descriptions and practical coaching advice based on your effort level.

I feel like I'm at an RPE of 14 on the Borg scale and my max HR is 190. What is my estimated heart rate?

Based on a Borg 6-20 RPE of 14 and a max HR of 190, your estimated heart rate is approximately 153 BPM, which places you in the Aerobic training zone.

Convert an RPE of 7 on the CR10 scale with a max HR of 185.

For a CR10 RPE of 7 and a max HR of 185, your estimated heart rate is approximately 148 BPM (70% of max), placing you in the Threshold training zone.

What kind of training should I do at an RPE of 18 on the Borg scale?

An RPE of 18 represents a very high intensity, typically corresponding to the Anaerobic/Maximal zone. This effort is characterized by intense muscular effort and is usually sustainable only for short durations.

The Borg 6-20 scale is a traditional method for measuring perceived physical exertion, where 6 represents no effort and 20 represents maximal intensity.
