The term 'Hebrew Unit of Dry Measure' refers to two units of measurement used in the Hebrew Bible. The first is the Ephah, which is a unit of dry measure equal to 10 omers and is roughly equivalent to 22 liters. The second is the Omer, which is a unit of dry measure equal to 1/10 of an ephah and is roughly equivalent to 2.2 liters. Both the Ephah and the Omer were used to measure grain and other dry goods in ancient times.
