How Converted Dosage Value Is Calculated

A converted dosage value represents the equivalent biological activity or weight of a substance when switched between milligrams (mg) and International Units (IU). Because IU measures biological effect rather than just weight, a specific equation is used to bridge the gap between these units.

Result = Amount × Conversion Factor

Where:

  • Amount = The numerical value you entered
  • Conversion Factor = Specific biological potency of the substance
  • Result = The converted value in the target unit
  1. Input the numerical amount and select the specific substance type, such as Vitamin D or Insulin. This identifies the correct biological potency needed.
  2. Choose your conversion direction (mg to IU or IU to mg). This tells the calculator which specific factor to apply to your number.
  3. Review the calculated result, which represents the equivalent dosage in the new unit. This final step ensures you understand the exact quantity you are taking.

What Your Converted Dosage Value Means

Your result shows exactly how much of a medicine or vitamin you are taking in a different unit of measure. This helps you compare different products easily and understand the true potency of your dose.

Vitamin D Supplementation: If you convert 0.025 mg, the result will show 1,000 IU. This helps confirm that a standard supplement capsule meets the daily recommended intake for bone health.

Insulin Management: For patients using insulin, converting 10 IU reveals it equals approximately 0.36 mg. This verification is critical when measuring liquids to ensure you are drawing the correct amount into a syringe.

Vitamin A Intake: Converting 900 mg of Vitamin A will result in roughly 3,000,000 IU. This highlights how massive IU values can get compared to milligrams for this nutrient.

Important: Remember that biological activity can vary by manufacturer. Always double-check the specific product label to confirm the conversion factor matches your specific medication formulation.
