This article is about the ancient Jewish unit of volume. For the body of water, see Sea. For the Singaporean violinist, see Lynnette Seah.
Seah is a unit of dry volume of ancient origin used in Halakha (Jewish religious law), which equals one third of an epha, or bath. Since the bath unit has been established to be 22 litre, 1 seah equals 7,33 liter or 7,33dm3.
