About IU to MG Conversion Tool

The IU to MG converter is a simple online tool that allows users to convert International Units (IU) to milligrams (MG), micrograms (MCG) and vice versa. It's especially helpful for vitamins where dosage is often expressed in IUs, such as:

• Vitamin D
• Vitamin E
• Vitamin A
• Vitamin C
• Vitamin K

Each vitamin has a different conversion factor based on its potency and biological activity. For example, 1 IU of Vitamin D equals 0.000025 mg, while 1 IU of Vitamin E is approximately 0.67 mg. And also 1 IU of Vitamin D equals 0.025 mcg, while 1 IU of Vitamin E is approximately 670 mcg.

Labeling Units of Measure

These are the labels used in the tool:

• mcg: microgram (μg). One millionth of one gram.
• mg: milligram. One thousandth of one gram.
• IU: International Unit is a measure of biological activity and is different for each substance.

In May 2016, the U.S. Food and Drug Administration (FDA) announced regulations that required changes to the Supplement Facts label related to the use of units of measure and their conversions. The new regulations started in 2020-2021 were mandatory. For more information from the FDA, for specific guidance on unit conversions, please click here.
