Percent Heart Rate Calculator

Formula

The formula to calculate the Percent Heart Rate (PHR) is:

\[ PHR = \left( \frac{CHR}{MHR} \right) \times 100 \]

Where:

\( PHR \) is the Percent Heart Rate (%)
\( CHR \) is the current heart rate (BPM)
\( MHR \) is the max heart rate (BPM)

What is Percent Heart Rate?

Percent heart rate refers to the percentage of your current heart rate relative to your maximum heart rate. This metric is often used in fitness and health to gauge the intensity of exercise and to ensure that individuals are working within their target heart rate zones for optimal cardiovascular benefits.

Example Calculation

Let's assume the following values:

Current Heart Rate (CHR) = 150 BPM
Max Heart Rate (MHR) = 200 BPM

Using the formula to calculate the Percent Heart Rate (PHR):

\[ PHR = \left( \frac{150}{200} \right) \times 100 = 75% \]

The Percent Heart Rate is 75%.
