Moisture Content Calculator
Calculate moisture content (%) on a dry basis using gravimetric method.
How to Use This Calculator
Measure wet weight
Weigh the sample before drying.
Dry and measure dry weight
Dry the sample to constant weight and record the dry weight.
Calculate percentage
Enter both weights and compute moisture content on dry basis.
Formula
MC% (dry basis) = (Ww − Wd) / Wd × 100%
Where: Ww is wet weight, Wd is dry weight.
Example: Ww = 120.5 g, Wd = 100 g ⇒ MC% = 20.5%.
About Moisture Content Calculator
Moisture content quantifies water held in materials. This tool computes dry-basis moisture content used in food science, soils, wood, and pharmaceuticals.
When to Use This Calculator
- Quality control: Verify moisture levels in products.
- Laboratory analysis: Gravimetric moisture determination.
- Process design: Drying/conditioning calculations.
Why Use Our Calculator?
- ✅ Accurate: Uses standard dry-basis definition.
- ✅ Easy: Only needs wet and dry weights.
- ✅ Clear: Shows formula and example.
Frequently Asked Questions
Dry basis vs wet basis?
Dry basis uses Wd in the denominator, often larger percentages; wet basis uses Ww in the denominator. Specify which your process requires.
Units for weights?
Any mass unit is fine as long as both are the same (e.g., grams or kilograms).
What if wet weight < dry weight?
This suggests an input error or mass loss beyond water (e.g., volatiles). Recheck measurements.
