The United States National Institute of Standards and Technology now recommends the use of the uppercase letter L, a practice that is also widely followed in Canada and Australia.
In these countries, the symbol L is also used with prefixes, as in mL and μL, instead of the traditional ml and μl used in Europe.
In the UK and Ireland, as well as the rest of Europe, lowercase l is used with prefixes, though whole litres are often written in full (so, "750 ml" on a wine bottle, but often "1 litre" on a juice carton).
In 1990, the International Committee for Weights and Measures stated that it was too early to choose a single symbol for the litre.
