Hoppus foot definition

Hoppus foot is a measure of volume from log to converted timber, accounting for loss. It is an imperial measure, used only in the British hardwood trade, and not in the softwood market. A Hoppus foot includes the rounded edges from which the cubic volume has to come. Therefore a Hoppus foot is larger than a cubic foot, i.e. there are fewer Hoppus feet in a cubic meter of timber.

1 m3 = 27.736074 Hoppus feet

1 m3 = 35.31467 Cubic feet

1 H ft = 0.03605 Cubic meter

Hoppus feet can be measured by the cubic meter and then converted. Alternatively, a Hoppus girth tape can be used for measuring logs. It is calibrated in quarter girth (QG) inches, and the cross-sectional area is approximated by squaring the QG and dividing by 144. A Hoppus foot is about 21% short of a true cubic foot.
