Wood may contain a varying amount of water. The dimensions of a piece of wood will vary with the amount of moisture present.
Parameters:
(1) original weight of a piece of wood in kilograms
(2) weight of the same piece of wood after kiln drying in kilograms
change in weight due to water loss =
= (original weight) - (weight after drying)
moisture content of the original piece of wood =
= ((original weight) - (weight after drying)) / (weight after drying) * 100%
