Enter the mass of iodine absorbed and the mass of the sample into the calculator to determine the iodine value of fats and oils. The iodine value is a measure of the unsaturation level of fats and oils.

Iodine Value Formula

The following formula is used to calculate the iodine value:

IV = (MI / SM) * 100

Variables:

  • IV is the iodine value (grams of I2 per 100 grams of sample)
  • MI is the mass of iodine absorbed by the sample (grams)
  • SM is the mass of the sample (grams)

To calculate the iodine value, divide the mass of iodine absorbed by the mass of the sample and then multiply by 100 to get the value in grams of iodine per 100 grams of sample.

What is an Iodine Value?

The iodine value is a common measure of the unsaturation level of fats and oils. It indicates the amount of iodine, in grams, that is consumed by 100 grams of a fat or oil sample. A higher iodine value indicates a higher degree of unsaturation, which usually corresponds to a lower melting point and a tendency to spoil more quickly due to oxidation.

How to Calculate Iodine Value?

The following steps outline how to calculate the iodine value:


  1. First, determine the mass of iodine absorbed by the sample (MI) in grams.
  2. Next, determine the mass of the sample (SM) in grams.
  3. Use the formula IV = (MI / SM) * 100 to calculate the iodine value.
  4. Finally, calculate the iodine value (IV) in grams of iodine per 100 grams of sample.
  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.

Mass of iodine absorbed by the sample (MI) = 1.5 grams

Mass of the sample (SM) = 50 grams
