Milliliter (mL)
The milliliter, symbol mL, is a metric unit of volume equal to one-thousandth of a liter. Introduced alongside the metric system in the late 18th century in France, it provides a practical measure for small liquid quantities, such as in cooking, pharmaceuticals, and laboratory work. One milliliter of water is approximately equal to one cubic centimeter, making conversions between mass and volume straightforward for water-based liquids. The milliliter’s adoption worldwide has standardized recipes, measurements, and scientific experiments, allowing for precision and consistency across countries.
Liter (L)
The liter (L) is a metric unit of volume, representing 1,000 milliliters. It originated in France as part of the metric system reforms of 1795, initially defined as the volume occupied by one kilogram of water at its densest point. Over time, the liter became a fundamental unit for measuring liquids in science, industry, and everyday life. Its decimal structure makes calculations and conversions straightforward, contributing to its widespread adoption around the world, even as some regions continue to use imperial measures in certain contexts.
