# Belgian units of measurement

Prior to adopting the metric system in 1816 a number of units of measurement were used in Belgium to measure different types of quantities including length, mass, area.^{[1]} Since 1820, International Metric System has been compulsory in Belgium, and in the starting, different names were used for units like meter, litre, kilogram, etc. ^{[2]}^{[1]}

## Pre-metric Units

Before 1820, different units were used in the area that now makes up Belgium. Belgium became an independent country in 1830.
