How to Calculate Moisture Content
1
Weigh the wet sample
Record the initial weight of your material before drying (Wet Weight).
2
Dry the sample completely
Use an oven at 103-105°C (217-221°F) until constant weight is achieved.
3
Weigh the dried sample
Record the final weight after drying (Dry Weight).
4

Formulas
Wet Basis (MC%wb)
MC%wb = (Ww - Wd) / Ww × 100
Ww = Wet Weight, Wd = Dry Weight
Range: 0% to <100% (water content relative to total weight)
Dry Basis (MC%db)
MC%db = (Ww - Wd) / Wd × 100
Ww = Wet Weight, Wd = Dry Weight
Range: 0% to ∞ (can exceed 100% for very wet materials)
Conversion Between Bases
Wet Basis
Dry Basis
MC%db = MC%wb / (100 - MC%wb) × 100
Dry Basis
Wet Basis
MC%wb = MC%db / (100 + MC%db) × 100
Pro Tips
- Agriculture & Food: Wet basis is commonly used for grains, feed, and food products.
- Wood Industry: Dry basis is standard for lumber and wood products (ASTM D4442).
- Soil Science: Both methods are used depending on the application.
- Quality Control: Always use consistent measurement methods for comparable results.
