The milliliter (mL) is a metric unit of volume commonly used to measure small quantities of liquid. It is one-thousandth of a liter, making it a handy unit in a variety of scientific, medical, and everyday contexts.
Historical Context§
The milliliter is part of the metric system, which originated in France during the late 18th century following the French Revolution. The metric system was designed to be a universal system of measurement based on natural constants. Over time, it was adopted globally due to its simplicity and ease of conversion.
Types/Categories of Measurement§
- Metric Units: Includes milliliters, liters, and kiloliters.
- Imperial Units: Includes fluid ounces, pints, quarts, and gallons.
Key Events§
- 1795: France officially adopts the metric system.
- 1875: The Metric Convention establishes the International System of Units (SI).
- 1960: The International System of Units (SI) is revised to include the milliliter as an official unit.
