Moisture Content Formula
The following formula gives wet-basis moisture content. Dry-basis moisture uses dry mass as the denominator instead.
Formula source: FAO – Farm Structures in Tropical Climates (Chapter 9: Crop handling, conditioning and storage)
- Where MC is wet-basis moisture content (%)
- w is the weight while wet
- d is the weight while dry
For wet-basis moisture, subtract dry mass from wet mass, divide by wet mass, then multiply by100. For dry basis, divide the same water mass by dry mass instead. The calculator also solves wet or dry mass from a percentage with its basis explicitly selected.
Moisture Content Definition
Moisture content expresses water mass relative to wet sample mass (wet basis) or dry sample mass (dry basis). The sample need not be saturated. Dry-basis content can exceed100%; it is undefined when dry mass is zero. The mass-loss method assumes only water is removed.
Moisture Content Example
How to calculate moisture content?
- First, determine the weight of the object while wet.
Using a scale, we find the object to be 20 g while wet.
- Next, determine the weight while dry.
After drying the object, we weigh it again and find that the weight is 10 g.
- Finally, calculate the moisture content.
Using the formula we find the moisture content to be 50%.
FAQ
Wet-basis moisture is water mass as a percentage of total wet mass; dry-basis moisture uses dry mass instead. State the basis whenever reporting a percentage.
