General-purpose (non-molded) hoses are sold in varying lengths (3-foot piece, 10-foot piece, 25-foot roll, etc.) To make comparison easy, prices are set in standard units (per foot, or per inch in some cases) and sold in "packs" equal to the length of the hose (for example, a 3-foot hose may be priced per inch and sold in packs of 36).
