* 1 cubic decimeter (dm³) is equal to 1000 milliliters (mL).
Why?
* A decimeter (dm) is equal to 10 centimeters (cm).
* A cubic decimeter (dm³) is a cube with sides of 10 cm each.
* The volume of this cube is 10 cm x 10 cm x 10 cm = 1000 cubic centimeters (cm³).
* 1 cubic centimeter (cm³) is equal to 1 milliliter (mL).
Therefore, 1 dm³ = 1000 cm³ = 1000 mL
