Enter the total parts per million (PPM) into the Grains From PPM Calculator. The calculator will evaluate the Grains From PPM.

## Grains From PPM Formula

The following two example problems outline the steps and information needed to calculate the Grains From PPM.

**G = PPM /17.1**

Variables:

- G is the Grains From PPM (grains/gallon)
- PPM is the total parts per million (PPM)

## How to Calculate Grains From PPM?

The following steps outline how to calculate the Grains From PPM.

- First, determine the total parts per million (PPM).
- Next, gather the formula from above = G = PPM /17.1.
- Finally, calculate the Grains From PPM.
- After inserting the variables 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.

total parts per million (PPM) = 1500

G = PPM /17.1** **= ?
