## Grain Test Weight Formula

The following formula is used to calculate the Grain Test Weight.

GTW = (100-D) / (100-W) * TW

Variables:

- GTW is the Grain Test Weight (lbs/bu)
- D is the dry moisture content (%)
- W is the wet moisture content (%)
- TW is the test weight at wet moisture content (lbs/bu)

## How to Calculate Grain Test Weight?

The following steps outline how to calculate the Grain Test Weight.

- First, determine the dry moisture content (%).
- Next, determine the wet moisture content (%).
- Next, determine the test weight at wet moisture content (lbs/bu).
- Next, gather the formula from above = GTW = (100-D) / (100-W) * TW.
- Finally, calculate the Grain Test Weight.
- 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.

dry moisture content (%) = 25

wet moisture content (%) = 15

test weight at wet moisture content (lbs/bu) = 50GTW = (100-D) / (100-W) * TW =** ** ?
