1) Production/capacity means an approximative sawmill size in production of sawn wood, lumber. For mills which have given figures in roundwood, logs, we have assumed a yield of 55%
2) One board foot is theoretically equal to 1 inch x 12 inch x 12 inch or 2360 liters. To convert a board foot to metric volume in m3 of sawn wood one have to take into consideration that in North America the real sawn dimension is less and in Europe the sawn dimension is more than the nominal. We have assumed the factor to be 1.6 m3 per Mfbm.
