What is the relationship between cubic centimeters (cm3) and milliliters (mL)

A cubic centimeter (cm³) and a milliliter (mL) are two units used to measure volume. They are exactly equal in magnitude:

1 cm³ = 1 mL

This means that a cube measuring 1 cm × 1 cm × 1 cm has a volume of 1 cubic centimeter, which is also the same as 1 milliliter of liquid.

Why Are They Equal?

The equality between cm³ and mL is based on the metric system, which was designed for simplicity and consistency:

• The liter (L) is the base unit of volume in the metric system.

• 1 liter = 1000 milliliters (mL).

• By definition, 1 liter = 1000 cubic centimeters (cm³).

• Therefore, since both 1 L = 1000 mL and 1 L = 1000 cm³, it follows directly that 1 cm³ = 1 mL.
