The Iodine Value Calculator determines the degree of unsaturation in fats and oils. Iodine value (IV) measures how many grams of iodine are consumed by 100 grams of lipid. It is widely used in food chemistry, biodiesel production, and oil quality testing in the United States.
A higher iodine value indicates more double bonds and greater unsaturation. This tool applies the standard titration formula used in laboratory analysis.
The iodine value measures the amount of iodine that reacts with double bonds in fatty acids.
IV = (B - S) * N * 12.69 / W
This formula calculates grams of iodine absorbed per 100 grams of sample.

Iodine value measures the degree of unsaturation in fats and oils by quantifying double bonds in fatty acids.
It helps determine oil stability, shelf life, and resistance to oxidation.
A high iodine value indicates more double bonds and higher unsaturation.
Low iodine value suggests saturated fats with fewer double bonds.
Yes. Biodiesel quality standards often include iodine value limits.
Grams of iodine per 100 grams of sample.
Indirectly. It indicates unsaturation, which affects oxidation stability.
Yes. It follows standard AOCS titration methodology.
It is a standard conversion factor derived from iodine molecular weight and unit adjustments.
Yes. The sample weight is directly proportional in the calculation formula.
