Hoppus foot definition
Hoppus foot is a measure of volume from log to converted timber, accounting for loss. It is an imperial measure, sometimes used in the 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
A Hoppus girth tape is used for measuring the Hoppus volume of logs, in conjunction with a booklet of Hoppus Tables. The tape is used to measure the girth in the middle of the log, giving the result in quarter girth (QG) inches. The length of the log is then measured in feet. One then turns to the relevant page of girths in the tables and looks down the central column for length in feet. Looking across the row, you then choose according to whether it was an exact QG inch, a quarter, half, or three quarters, to get the right reading.
Confused? Its not that bad! Just buy the tape and tables and all will be clear.
