korntunna [Icelandic]

In Iceland, ? – 19ᵗʰ centuries, a unit of capacity = 4½ cubic fet = 144 pottar = 8 skeppa each of 18 pottar. It corresponds to the Danish dry tønde, about 139.12 liters. It was used not only for grain, but also fruit, salt, chalk, lime and other products.

As in most of the world, grain sales switched from measurement by volume to measurement by weight, and by the 20ᵗʰ century the korntunna was largely replaced by the hálftunna of 100 pounds.
