Metric Weights and Measures and Conversions
- Units legally used in business in France
- How to convert the metric system of weights and measures into their Imperial equivalents and vice versa
In general, weights & measures in France and the Continent are metric.
Credit for originating the metric system is usually given to Gabriel Mouton, a French vicar, somewhere around 1670, but the basis of the system we know today was designed during the French Revolution in the 1790’s, and brought order out of the conflicting and confusing traditional systems of weights and measures then being used in Europe.

The USA and UK
With the switch of the UK to the metric system (although not completely), only the USA still uses the weights and measures system it inherited from Britain. However, although some American measures have the same name as old English measures, they’re not the same…
- The American pint has 16 fluid ounces whereas the UK pint has 20 fluid ounces (US=473.176473 ml UK=568.26125 ml)
Note: this is especially important to note when ordering a beer!
- The American gallon has 8 pints as does the UK but the measure is different
- (US=3.785411784 Litres UK=4.54609 Litres)
People in Britain still commonly refer to the old traditional measurements though.
