# Brereton Log Rule Calculator

### Calculate the Board Feet of a Log using the Brereton Log Rule.

Two diameter measurements shall be taken under bark at
each log end perpendicular to each other (at both ends) and
the final recorded diameter shall be the average of the two measurements.

Brereton's board foot value is calculated from cubic feet of log * 12.
