What is the SI unit for volume?

• A. Liter (L)
• B. Cubic meter (m^3)
• C. Gallon (gal)
• D. Pint (pt)

Answer: (A)

Volume is measured in cubic meters in the SI system. Because length is the base dimension, volume comes from length cubed, so the standard SI unit is the cubic meter (m^3). The liter is a commonly used unit, but it is not an SI unit; it’s defined as a cubic decimeter and equals 0.001 m^3. In everyday lab work, liters are convenient for liquids, yet the official SI unit remains the cubic meter. For reference, 1 L = 0.001 m^3. Gallons and pints come from other measurement systems and are not SI units.
