Enter the absolute humidity and temperature into the calculator to determine the running humidity. This calculator can also evaluate any of the variables given the others are known.

## Running Humidity Formula

The following formula is used to calculate the running humidity.

RH = (AH / (T + 273.15)) * 100

Variables:

• RH is the running humidity (%) AH is the absolute humidity (g/m³) T is the temperature (°C)

To calculate the running humidity, divide the absolute humidity by the sum of the temperature and 273.15 (to convert it to Kelvin). Multiply the result by 100 to get the running humidity in percentage.

## What is a Running Humidity?

Running humidity refers to the amount of moisture or water vapor present in the air while a person is running or jogging. It is an important factor to consider as high humidity can make running more challenging by reducing the body’s ability to cool itself through sweat evaporation. This can lead to overheating, dehydration, and decreased performance. Therefore, runners often need to adjust their pace and hydration strategies in humid conditions.

## How to Calculate Running Humidity?

The following steps outline how to calculate the Running Humidity.

1. First, determine the absolute humidity (AH) in g/m³.
2. Next, determine the temperature (T) in °C.
3. Next, use the formula RH = (AH / (T + 273.15)) * 100 to calculate the Running Humidity.
4. Finally, calculate the Running Humidity.
5. After inserting the values of AH and T into the formula and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

Absolute humidity (AH) = 12 g/m³

Temperature (T) = 25°C
