About This Calculator
This calculator converts between milligrams (mg) and micrograms (mcg), commonly used in medication dosing and nutritional labeling. It supports high-precision mass conversions for healthcare and science.
How It Works
- Select the conversion direction: mg to mcg or mcg to mg.
- Enter the value to convert.
- The conversion is based on these formulas:
mcg = mg × 1000
mg = mcg ÷ 1000
Note: mcg and μg are equivalent. mcg is commonly used in medical contexts for clarity.
