Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Wet-basis moisture. Assumes mass loss reflects water and the drying procedure is appropriate for the material.
Example Calculation
- Wet sample mass: 100 g
- Oven-dry mass: 25 g
Wet sample mass = 100; Oven-dry mass = 25. Primary result: 25.
Frequently asked questions
How do I use this calculator?
Enter wet sample mass, oven-dry mass. The result updates automatically. Use Reset to restore the example values.
What method does it use?
dry matter%=100 dry/wet; moisture%=100−dry matter%.. Wet-basis moisture. Assumes mass loss reflects water and the drying procedure is appropriate for the material.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
