Enter the initial and final weight of a sample into the calculator to determine the moisture loss percentage. This calculator helps in determining the loss of moisture content from a material.

Moisture Loss Formula

The following formula is used to calculate the moisture loss percentage:

ML = ((IW - FW) / IW) * 100

Variables:

  • ML is the moisture loss (%)
  • IW is the initial weight of the sample (grams)
  • FW is the final weight of the sample (grams)

To calculate the moisture loss percentage, subtract the final weight from the initial weight, divide by the initial weight, and then multiply by 100 to get the percentage.

What is Moisture Loss?

Moisture loss refers to the reduction in weight of a material due to the evaporation or removal of water content. It is an important parameter in various industries such as food processing, agriculture, and construction, where the moisture content can affect the quality, shelf life, and structural integrity of products and materials.

How to Calculate Moisture Loss?

The following steps outline how to calculate the moisture loss percentage:


  1. First, determine the initial weight of the sample (IW) in grams.
  2. Next, determine the final weight of the sample (FW) in grams after drying or exposure to conditions causing moisture loss.
  3. Use the formula ML = ((IW – FW) / IW) * 100 to calculate the moisture loss percentage (ML).
  4. Finally, calculate the moisture loss percentage.
  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.

Initial weight of the sample (IW) = 200 grams

Final weight of the sample (FW) = 180 grams
