Meaning & context

Ratal

≈ 0.7938 kg

A commercial weight. The tables divide the rotolo into 30 ounces and give about 793.8 g. This rounded value should not be read as a standard for every period.

Uqija

≈ 0.0265 kg

The Maltese uqija is a fraction of a ratal. The translation ounce can mislead: it is not an English ounce.

Wiżna

≈ 3.969 kg

A group of five ratal. The tables use Pesa for five rotoli; this conversion follows that relationship using the rounded ratal basis.

Qantar

≈ 79.38 kg

A large weight. The tables give a cantar as 20 pesa, or 100 ratal. It is not the metric quintal of 100 kg.

Kwart · ¼ ratal

≈ 0.1985 kg

A quarter of the historical ratal, here about 198.45 g. The secondary reference reports this meaning alongside a quarter of an uqija. It is not a quarter kilogram or the liquid kwarta.

Kwart · ¼ uqija

≈ 0.0066 kg

A quarter of a Maltese uqija: here about 6.615 g. The tables divide an Ounce into four quarti. It is much smaller than a quarter of a ratal, so the parent unit must be known.

Half ratal

≈ 0.3969 kg

Half a ratal is a fraction of a specified ratal: about 396.9 g using the rounded historical basis of 793.8 g per ratal. It is not half a kilogram.

Three quarters of a kilogram

= 0.75 kg

Tliet kwarti means three of four equal parts. In this expression the whole is one kilogram: three quarters of a kilogram is exactly 750 g.
