1. What is Dry Matter Calculation?

Dry matter calculation determines the mass of a material after all moisture has been removed. It's essential in agriculture, food science, and material testing to understand the true solid content of a substance.

2. How Does the Formula Work?

The calculator uses the dry matter formula:

\[ DM = wet\_weight \times \left(\frac{100}{100 - moisture}\right) \]

Where:

\( DM \) — Dry matter (g)
\( wet\_weight \) — Weight of the sample with moisture (g)
\( moisture \) — Moisture content (%)

Explanation: The formula calculates the theoretical weight of the sample if all moisture were removed, based on the percentage of moisture present.

3. Importance of Dry Matter Calculation

Details: Dry matter content is crucial for nutritional analysis, quality control, and accurate comparison between samples with different moisture contents.

4. Using the Calculator

Tips: Enter wet weight in grams and moisture content as a percentage (0-99.99%). Both values must be positive numbers, with moisture less than 100%.

5. Frequently Asked Questions (FAQ)

Q1: Why calculate dry matter instead of using wet weight?
A: Dry matter provides a consistent basis for comparison by eliminating variability caused by moisture content.

Q2: What's a typical moisture range for agricultural products?
A: Varies widely - fresh forage might be 70-85%, grains 10-15%, and hay 10-20%.

Q3: How is moisture content determined?
A: Typically by oven drying a sample at 105°C until constant weight is achieved.

Q4: Can this formula be used for any material?
A: Yes, as long as the moisture content is accurately known and below 100%.

Q5: What's the difference between dry matter and dry basis?
A: They're essentially the same concept - both refer to the material excluding its water content.
