MC % Measured on Oven Dried Basis Calculators

Moisture content measured on a dry basis can exceed 100%. Convert dry basis MC% to wet basis MC% Moisture content can be measured based on dry basis or wet basis. If the dry basis moisture content % (MCdry) is known it can be converted to wet basis moisture (MCwet) content percentage. MCcwet% = MCdry/ (100 + MCdry)*100; Firewood Calculators
