What Is the Wood Moisture Shrinkage & Dimensional Change Calculator?
Dimensional wood movement (shrinkage and swelling) occurs strictly below the Fiber Saturation Point (~28-30% MC) as bound water leaves cell walls.
How Does the Wood Moisture Shrinkage & Dimensional Change Calculator Work?
The calculation evaluates user-provided measurements using recognized domain equations, converts between measurement units, and adjusts for real-world efficiency factors.
Wood Moisture Shrinkage & Dimensional Change Calculator Formula & Variables
The core mathematical equation utilized by this calculator is expressed as:
Water loss above FSP represents free water in cell cavities and induces no dimensional change in defect-free wood.
