Dry matter basis conversion calculator

Converts an as-fed nutrient percentage to a dry-matter basis using moisture content.

What this calculator does

Dry matter basis conversion works out converts an as-fed nutrient percentage to a dry-matter basis using moisture content. Enter your own figures above and the answer updates as you type: nothing is fixed in the code, so the result reflects exactly the numbers you supply.

The formula this calculator evaluates is printed under the tool and explained below, so you can check the working by hand or reuse it in a spreadsheet.

The formula

FormulaDMB% = AFB% × 100 / (100 − moisture%)

The inputs explained

FieldWhat to enter
As-fed nutrient percentage (%)A number, measured in %. Starts at 25.
Moisture content (%)A number, measured in %. Starts at 10.

Worked examples

Every figure in the tables below is produced by this page’s own calculator at build time, so the numbers and the tool always agree. Select any row to load that scenario.

How the answer changes with as-fed nutrient percentage
