Understanding the Difference: Is 1 mg 1 mL?

Learn why 1 mg is not the same as 1 mL and how to convert between weight and volume based on density.

No, 1 mg is not 1 mL. Milligrams (mg) measure weight, while milliliters (mL) measure volume. The relationship between them depends on the substance's density. For example, water has a density of 1 g/mL, so 1 mg of water is 0.001 mL. Always check the substance's density to convert accurately.

FAQs & Answers

  1. How do you convert mg to mL? To convert mg to mL, you need to know the density of the substance. Use the formula: mL = mg / (density in g/mL).
  2. What is the relationship between weight and volume? Weight measures the mass of a substance, while volume measures the space it occupies. Their relationship is determined by the substance's density.
  3. Can all substances be converted between mg and mL? No, conversions depend on the specific density of each substance. Water is a common reference point due to its density of 1 g/mL.
  4. What does density mean? Density is defined as mass per unit volume, commonly expressed in grams per milliliter (g/mL) in scientific contexts.
