Understanding the Difference: 1 mL vs 1 mg

Learn why 1 mL is not equal to 1 mg and how to convert between volume and mass based on substance density.

No, 1 mL does not equal 1 mg. Milliliters (mL) measure volume, while milligrams (mg) measure mass. Their equivalence depends on the substance's density. For example, 1 mL of water equals 1 gram (1000 mg) since water's density is 1 g/mL. For other substances, you'll need to know the density to convert between mL and mg.

FAQs & Answers

  1. What is the relationship between milliliters and milligrams? Milliliters measure volume while milligrams measure mass; their conversion depends on the density of the substance.
  2. How do you convert mL to mg? To convert mL to mg, multiply the volume in mL by the substance's density in g/mL to get the mass in mg.
  3. Does density affect conversions between mL and mg? Yes, the density of a substance is crucial for converting between mL and mg, as different substances have different densities.
  4. Can 1 mL equal 1 mg for all substances? No, 1 mL equals 1 mg only for substances with a density of 1 g/mL, such as water; for others, the conversion varies.
