Maltese units of measurement
In modern usage, metric is used almost exclusively in commercial transactions. These units are mostly historical, although they are still used in some limited contexts and in Maltese idioms and set phrases. Many of these terms are directly related to Arabic units. The Weights and Measures Ordinance of 1921 established uniformity in the conversion of such weights and measures. All these measures were defined as simple multiples of the Imperial units then in use in Britain.

Length
Length units were typically used for measuring goods and building sizes. Distances were traditionally measured in terms of travel time, which explains the lack of large scale units.

This is equal to 10 pounds of water at a specified temperature and air pressure. This (~4.546 090 31 litres) is slightly larger than the modern definition (exactly 4.546 09 litres).
