Conversions

Converting cubic tons (i.e., volumes) to measures of weight presents difficulties because organic materials such as timber vary in density.

Approximate volume conversions, based on a timber cubic ton of 40 cubic feet:
* 1 ton (40 cubic feet) = 1.133 cubic metres
* 1 cubic metre = 0.883 cubic tons (35.32 cubic feet)
