To convert 30 mg to mL, you need the substance's density because mg (milligram) is a unit of mass and mL (milliliter) is a unit of volume. The formula is: Volume (mL) = Mass (mg) / Density (mg/mL). Without knowing the substance's density you're referring to, a direct conversion isn't possible. Different substances have different densities. For example, if the substance is water which has a density of 1 mg/mL, then 30 mg would be 0.03 mL.

FAQs & Answers

  1. Can you convert mg to mL without knowing the density? No, converting milligrams (mg) to milliliters (mL) requires knowing the substance's density since mg measures mass and mL measures volume.
  2. What is the formula to convert mg to mL? The formula is Volume (mL) = Mass (mg) divided by Density (mg/mL). You must know the density of the substance to use this formula.
  3. What is the density of water used for mg to mL conversion? The density of water is approximately 1 mg/mL, which means 30 mg of water equals 0.03 mL.
