What is the equivalent of 1 milliliter in cubic centimeters?

One milliliter is defined as exactly one cubic centimeter. This is a fundamental conversion in the metric system where the liter is the base unit of volume. Since a milliliter is one-thousandth of a liter, and a cubic centimeter is also one-thousandth of a liter, it directly follows that they are equal in volume measurement. Therefore, when converting milliliters to cubic centimeters, they have a one-to-one correspondence, meaning that 1 milliliter equals 1 cubic centimeter. This relationship is foundational in many scientific and medical calculations, making it crucial to understand and remember.
