Enter the dry moisture content (%), the wet moisture content (%), and the test weight at wet moisture content (lbs/bu) into the Grain Test Weight Calculator. The calculator will evaluate the Grain Test Weight. 

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.

  1. First, determine the dry moisture content (%).
  2. Next, determine the wet moisture content (%). 
  3. Next, determine the test weight at wet moisture content (lbs/bu). 
  4. Next, gather the formula from above = GTW = (100-D) / (100-W) * TW.
  5. Finally, calculate the Grain Test Weight.
  6. 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 =  ?
