Millilitre en Pint (US) Convertisseur

A milliliter (symbol: ml or mL) is a metric unit of volume equal to one one-thousandth of a liter (0.001 L). It is part of the International System of Units (SI) and is equivalent to one cubic centimeter (1 cm³ = 1 ml). One milliliter of water has a mass of approximately one gram at standard temperature and pressure, reflecting the elegant relationship between metric units of volume and mass. The milliliter is one of the most widely used units of volume for liquids in everyday life worldwide. Beverages, medicines, cosmetics, and laboratory solutions are routinely measured and labeled in milliliters. The milliliter provides a practical scale for volumes too small to express conveniently in liters but too large to require microliters. In cooking, the milliliter is the standard unit for liquid measurements in countries that use the metric system. European and Australian recipes specify liquid ingredients in milliliters, while US recipes use cups and fluid ounces — making ml-to-cup conversion one of the most common cooking measurement conversions globally.

The milliliter was introduced as part of the French metric system in the late 18th century, defined as one one-thousandth of a liter. The liter itself was originally defined as the volume of one kilogram of water, establishing the fundamental link between metric units of mass and volume. This relationship made the milliliter a natural unit for pharmaceutical and scientific applications where mass-volume equivalences are important. The milliliter has been part of the International System of Units (SI) since its formalization, though the SI technically recognizes the liter as a non-SI unit accepted for use with SI, making the milliliter equally accepted. The symbol "mL" (with capital L) was adopted to avoid confusion with the numeral "1" in some typefaces. As the metric system spread globally through the 19th and 20th centuries, the milliliter became the universal standard for liquid measurement in medicine, science, and everyday commerce in most countries.

The milliliter is the standard unit for measuring liquid medicines worldwide. Drug dosages for syrups, suspensions, and injectable medications are specified in milliliters, and medical syringes are graduated in milliliters for precise dosing. Nutritional drinks, sports beverages, and dietary supplements globally list volumes in milliliters. In cooking and food preparation, milliliters are used in metric-system countries for liquid ingredients. Recipes in Europe, Australia, and Asia specify water, milk, oil, and other liquids in milliliters. Laboratory measurements in chemistry, biology, and pharmaceutical research rely heavily on milliliters for quantifying reagents and samples. Cosmetics and personal care products internationally label volumes in milliliters, making it the universal language of liquid volume.
