Tonnage

TONNAGE COMPUTATION

Once the density (in pounds per cubic feet) and the volume (in cubic feet) are known, total tons of coal in the stockpile can be readily determined (usually referred to as “wet” tons because the coal is exposed to atmosphere in its natural state), using the following calculation:

Wet tons of coal = Volume (ft3) x Density (lbs/ft3) / 2,000 lbs
