4.393 sq m	18.735 sq m	187.354 sq m	1124.124 sq m	4496.5 sq m	1.798 hectares

The above table is largely based on data provided by the government of Malta to the United Nations in the mid-20^th century¹. The names of the units are Maltese.

A century earlier, during the British occupation, a British author² described a predecessor system of land units based on the southern Italian measures prevalent in Malta during the previous centuries. Except for the canna, the units are seed measures of land. (Martin mentions “square tumoli,” but the tumolo is not a linear unit.) Taking the mid-19^th century value of the canna at Pouchet's 2.0880 meters (reported by Doursther, page 83) gives the following result:

		salma
	tumolo	16
square canna	256	4096
5.214 sq yd	0.276 acre	4.41 acres
4.360 sq m	1116.09 sq m	1.7857 hectares

Martin, however, states that the salma was 4.44 acres, which may be due to taking the a commercially convenient conversion, 3½ palmi = 1 English yard, which makes the canna about 2.090 meters. That equivalence seems to have rippled through Maltese measures.
