Convert the other way: % HRR to bpm
What it means
How hard is that?
Maximum heart rate from 220 − age, which can be off by 10–20 bpm for an individual. Heart rate reserve assumes a resting rate of 60 bpm. Not medical advice.
The math
How to convert bpm to % HRR
bpm = % × (220 − age); Karvonen: bpm = rest + % × (max − rest).
Example: 162 bpm = 78.4615 % HRR.
Heart rates on this page are for age 30 (max 190 bpm). Pick your age above.
