Understanding the Difference: Is 0.5 mL Equal to 1 mg?
Learn why 0.5 mL is not equal to 1 mg and how density affects measurement in cooking and medication.

0.5 mL is not equal to 1 mg. Milliliters (mL) measure volume, while milligrams (mg) measure mass. The conversion between them depends on the substance's density. For water, approximately 0.5 mL equals 500 mg since the density of water is close to 1 g/mL. To convert accurately, multiply the volume in mL by the density of the substance to find the mass in mg. Understanding this distinction is crucial for accurate measurement in cooking, medication, and other fields.**
FAQs & Answers
- How do you convert mL to mg? To convert milliliters (mL) to milligrams (mg), you need to know the density of the substance. Use the formula: mass (mg) = volume (mL) × density (g/mL).
- Is 1 mL equal to 1 g for all substances? No, 1 mL is not always equal to 1 g. This equivalence is true only for water and substances with a density of 1 g/mL. Other substances will have different conversions based on their density.
- Why is it important to understand the difference between mL and mg? Understanding the difference between mL (volume) and mg (mass) is essential for accurate dosage in medication, cooking, and scientific measurements, as using incorrect conversions can lead to serious errors.
- What is the density of water in g/mL? The density of water is approximately 1 g/mL at room temperature, which makes conversions between mL and mg straightforward for water.
