To convert milligrams (mg) to milliliters (ml), you need to know the density of the substance you are converting, since milligrams measure mass and milliliters measure volume. The relationship between mass and volume depends on the substance’s density.
For example:
- For water (density of 1 g/mL or 1000 mg/mL), 750 mg would be equal to 0.75 milliliters (since 750 mg ÷ 1000 mg/mL = 0.75 mL).
For other substances, you would need to know the density to perform an accurate conversion.
