Enter the total weight lost and the total original weight into the Calculator. The calculator will evaluate the Grain Shrinkage. 

Grain Shrinkage Formula

GS = WL / OW * 100

Variables:

  • GS is the Grain Shrinkage (%)
  • WL is the total weight lost
  • OW is the total original weight

To calculate Grain Shrinkage, divide the total weight lost by the original weight, then multiply by 100.

How to Calculate Grain Shrinkage?

The following steps outline how to calculate the Grain Shrinkage.


  1. First, determine the total weight lost. 
  2. Next, determine the total original weight. 
  3. Next, gather the formula from above = GS = WL / OW * 100.
  4. Finally, calculate the Grain Shrinkage.
  5. 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 weight lost = 400

total original weight = 2000

FAQs on Grain Shrinkage

What factors can affect grain shrinkage?
Various factors such as moisture loss, mechanical handling, and environmental conditions can significantly affect grain shrinkage.

How can one minimize grain shrinkage during storage?
Minimizing grain shrinkage can be achieved through proper drying, temperature control, and careful handling of the grain during loading and unloading.

Is it possible to calculate grain shrinkage for different types of grains?
Yes, while the basic principle remains the same, the specific weight loss and original weight values will vary depending on the type of grain being calculated.

Why is understanding grain shrinkage important for farmers and grain storage facilities?
Understanding grain shrinkage is crucial for accurate inventory management, determining saleable weight, and optimizing profit margins by minimizing losses.
