Equilibrium Moisture Content
Equilibrium Moisture Content is a measure of the moisture content of wood held in an environment with a consistent temperature and relative humidity for such a period of time that the moisture content stabilizes.
The non-climate-controlled values generated by this calculator are based on the data and formulas published by the USDA Forest Products Laboratory's "Equilibrium Moisture Content of Wood in Outdoor Locations in the United States and Worldwide" and provide a range of possible EMC values for wood and wood products in outdoor or non-climate controlled environments for which ranges of average temperatures and realtive humidity levels are known.
