Enter the total amount of precipitation (in) and the total amount of time (hrs) into the Precipitation Rate Calculator. The calculator will evaluate the Precipitation Rate.

## Precipitation Rate Formula

The following two example problems outline the steps and information needed to calculate the Precipitation Rate.

PRR = P / T
• Where PRR is the Precipitation Rate (in/hr)
• P is the total amount of precipitation (in)
• T is the total amount of time (hrs)

To calculate the precipitation rate, divide the total amount of precipitation by the total amount of time.

## How to Calculate Precipitation Rate?

The following example problems outline how to calculate Precipitation Rate.

Example Problem #1:

1. First, determine the total amount of precipitation (in).
• The total amount of precipitation (in) is given as: 3.
2. Next, determine the total amount of time (hrs).
• The total amount of time (hrs) is provided as: 2.
3. Finally, calculate the Precipitation Rate using the equation above:

PRR = P / T

The values provided above are inserted into the equation below and computed.

PRR = 3 / 2 = 1.5 (in/hr)

Example Problem #2:

For this problem, the variables required are provided below:

total amount of precipitation (in) = 4

total amount of time (hrs) = 1
