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 and some to Sicilian 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.

Table of length units
Unit	Plural	Relative value	Metric value	Imperial value	Notes
pulzier	pulzieri	1⁄12	~2.183 cm	~0.8594 in	The Maltese inch. Exactly 55⁄64 imperial inches.
fitel	iftla	1⁄2	~13.1 cm	~5.156 in	This unit is not in the 1921 act.
xiber	xbar	1	~26.19 cm	~10.31 in	The Maltese hand span, equivalent to the foot. Exactly 10 +5⁄16 imperial inches.
qasba	qasab, qasbiet	8	~2.096 m	~2.292 yd	This is exactly 82+1⁄2 inches, or 6 ft 10+1⁄2 in. It corresponds to the fathom, but was used in both land and sea contexts.

Area

Land

In 1921, these units were redefined with respect to the British Imperial standard. These values reflect this change.

Unit	Plural	Relative value	Metric value	Imperial value	Notes
kejla	kejliet	1⁄60	~18.74 m²	~22.41 sq yd
siegħ	sigħan	1⁄6	~187.4 m²	~224.1 sq yd
tomna	tomniet, or tmien	1	~1,124 m²	~1344 sq yd	exactly 5⁄18 acre, or 12,100 square feet. This unit is also exactly 256 qasba kwadru. Sometimes called a tumolo in English texts. Also called Tumoli with modern real estate agents Cf. dunam.

Volume

These units were all (except for the cubic units) defined in 1921 relative to the British Imperial gallon, which was defined in the 1824 act. This is equal to 10 pounds of water at a specified temperature and air pressure. This (~4.54609031 litres) is slightly larger than the modern definition (exactly 4.54609 litres).

Beer, wine, and spirits measure

None of the units from this group are mentioned in TY Maltese.

pinta	pinet	1⁄8	~142.1 ml	1⁄4 pt

Dry

None of these units are mentioned in TY Maltese. Note that there are two conflicting values for the siegħ (1⁄10 and 1⁄6 tomna, respectively).

Table of volume (dry) units
Unit	Plural	Relative value	Metric value	Imperial value	Notes
lumin	lumini	1⁄600	~30.31 ml	~1.849 cu in
kejla	kejliet	1⁄60	~303.1 ml	~18.49 cu in	also called a mondell
siegħ	sigħan	1⁄10	~1.818 L	~111 cu in	This is the value listed for the siegħ by Aquilina. The 1921 Act has a different value. This amount is exactly 3+1⁄5 imperial pints.
għabara		1⁄6	~3.031 L	~184.9 cu in, or ~0.107 cu ft	Referenced in Aquilina only. The 1921 Act uses this value for the siegħ, and does not mention the għabara by name.
tomna	tmien, or tomniet	1	~18.18 L	~0.6422 cu ft	Sometimes called the tumolo in English texts. This is exactly 4 imperial gallons.
modd	mdied	16	~290.9 L	~10.27 cu ft, or ~0.3805 cu yd	'weigh'. An alternate name given by Aquilina is the salma. This is exactly 64 imperial gallons.

Mass

All the Maltese mass units were redefined relative to the British Imperial ton in 1921. Before this, the units were presumably based on an Arabic standard. All equivalent measures listed in pounds below are exact values.

Note: there are two distinct units which are named kwart.

ottav	ottavi	1⁄8 uqija	~3.307 g	7⁄60 oz	'eighth'. Referenced in 1921 Act only.

Money

This system was used during the rule of the Knights of St. John in Malta. Subsequent currencies in use were sterling and the Maltese pound. Malta has since adopted the euro.
