1. What is IU To NG Conversion?

IU (International Units) to ng (nanograms) conversion is used to translate biological activity measurements (IU) to mass measurements (ng) for various substances like vitamins, hormones, and medications. The conversion factor is substance-specific.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( IU \) — International Units value
• \( \text{Conversion Factor} \) — Substance-specific conversion factor (ng/IU)
• \( ng \) — Result in nanograms

Explanation: The conversion factor varies by substance and must be obtained from reliable sources or product specifications.

3. Importance of Unit Conversion

Details: Accurate unit conversion is essential for proper dosing, scientific research, and comparing different formulations of the same substance.

4. Using the Calculator

Tips: Enter the IU value and the appropriate conversion factor for your specific substance. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find conversion factors?
A: Conversion factors are typically provided in product specifications, pharmacopeias, or scientific literature for each specific substance.

Q2: Are conversion factors the same for all substances?
A: No, conversion factors vary significantly between different substances and even between different forms of the same substance.

Q3: Why are some substances measured in IU instead of mass?
A: IU measurements are used when biological activity is more important than mass, particularly for substances that may have different potencies in different forms.

Q4: Can I use this calculator for medication dosing?
A: Always consult healthcare professionals for medication dosing. This calculator is for informational purposes only.

Q5: How precise are these conversions?
A: Precision depends on the accuracy of the conversion factor, which may vary between manufacturers and formulations.
