The butt was a measure of liquid volume equalling two hogsheads. This equated to 108 imperial gallons (490 l) for ale or 126 imperial gallons (570 l) for wine (also known as a pipe).
A traditional unit of volume for stone and other masonry. A perch of masonry is the volume of a stone wall one perch (16 1⁄2 feet or 5.03 metres) long, 18 inches (45.7 cm) high, and 12 inches (30.5 cm) thick. This is equivalent to exactly 24 3⁄4 cubic feet (0.92 cubic yards; 0.70 cubic metres; 700 litres).
