Forestry Wood and Forest Product Conversion Factors

Approximate Conversions of the Most Common Units of Wood Measure

Wood can be measured in a number of ways, which means that foresters, loggers, and timber owners can find themselves needing to convert some of these measurements. In order to understand those conversions, you first need to know some of the common terminology:

  • A standard cord is a four-foot by four-foot by eight-foot stack of wood.
  • A board foot is a wood plank that measures one-inch by 12-inches by one-inch.
  • MBF means thousand board feet.
  • A log rule is a tabular system used in determining the net volumetric yield of a log.
  • One cubic foot is equivalent to a 12-foot by 12-foot by 12-foot solid cube of wood.

Here is a list of the types of conversions commonly made in the wood industry. When it comes to executing these, online converters are helpful.
