The History of the Word
The word milliliter, also commonly referred to as millilitre, came into English in the early 1800’s from the French word millilitre, which was simply a combination of milli- and -liter. Mille meant “one thousandth” in Latin, and litra meant “one pound.”
Since 1799, liters have been used as units of measurement within the metric system, and they are still used as a base unit to this day. From this base unit, other metric units, like millimeters, are derived. Outside the United States, many countries in the rest of the world use the International System of Units and the metric system originally developed by the French.
When to Use the Abbreviation
The abbreviation ml. should be used wherever brevity and extra space are needed. This can include recipes, formulas, academic papers, notes, edits, etc. When it comes to academic and research papers, this abbreviation is commonly accepted in most scenarios and contexts. However, for research papers or formal writing that is not scientific in nature, it would be wise to include the full word with the abbreviation in parentheses the first time the word is used.
The word milliliter should be used in documents and written works that employ the metric system. For readers in the United States, fluid ounces (fl oz) may be used instead.
