Weight of Wood Species at various Moisture Contents

Weight of green and air-dry fuelwood of various species

The amount of bound water in wood is determined by the relative humidity (RH) of the surrounding atmosphere and the amount of bound water in the wood changes slowly as the relative humidity of the air changes.

The moisture content of wood is at its equilibrium moisture content when a balance is established at a given relative humidity.
