Quick Formulas
- If Lumber is full sawn, or footage is computed on actual sizes, multiply the board footage expressed in thousands of board feet (MBF) by 2.358 to find cubic meters:
MBF x 2.358 = m3
- If lumber footage is based on nominal sizes, divide the actual cross section (thickness x width) by the nominal cross section (thickness x width), then multiply by 2.358. Multiply the total board footage (MBF) by this figure to find the total cubic meters:
Actual Cross Section / Nominal Cross Section x 2.358 x MBF = m3
- If the lumber is trimmed to a specific length, but billed on an even foot basis, as in precision end-trimmed studs, then account for this difference by multiplying the total cubic meters (found by either of the above formulas or the chart) by an additional factor. To find this factor, divide the actual trim length by the nominal length, then multiply the total cubic meters by this number:
Actual Trim / Nominal Length x m3 = total m3

Metric Conversion Chart
The Key figure in Bold in the centre column can be read as either the metric or the British measure, thus 1 metre = 1.094 yards or 1 yard = 0.914 metres.
