How do I convert as-fed grain mass to dry matter?

Enter the as-fed mass (e.g., pounds or kilograms), the moisture percentage, and the bulk density (e.g., lb/ft³ or kg/m³). The calculator subtracts moisture to find dry matter and divides by bulk density to estimate volume.

What units does the calculator use?

The calculator accepts as-fed mass in pounds or kilograms, moisture as a percentage, and bulk density in pounds per cubic foot or kilograms per cubic meter. Results show dry matter mass and volume in corresponding units.

Why is bulk density needed for volume?

Bulk density (mass per unit volume) varies with grain type and moisture. Dividing dry matter mass by bulk density gives an estimate of volume, which is useful for storage bin sizing or feed ration planning.

As-fed grain mass

Moisture

As-fed bulk density

Results update automatically as you type.

Dry matter = as-fed mass × (1 − moisture ÷ 100); volume = as-fed mass ÷ entered bulk density. Moisture and density are user measurements; no commodity default is used.

Use Cases

Feed Ration Planning

Determine the dry matter content of grain to accurately formulate livestock rations, ensuring correct nutrient intake.

Example: Convert 1000 lb of corn at 15% moisture to dry matter for a feed mix.

Storage Volume Estimation

Estimate the volume of grain needed for storage based on dry matter mass and bulk density, helping plan bin capacity.

Example: Calculate cubic feet required for 5000 kg of wheat at 12% moisture.

Tips & Common Mistakes

Tips

Always measure moisture content accurately using a calibrated moisture meter for best results.
Use the correct bulk density for your specific grain type; values vary (e.g., corn ~45 lb/ft³, wheat ~48 lb/ft³).
Double-check unit consistency: if mass is in pounds, use bulk density in lb/ft³ to get volume in cubic feet.
For multiple batches, calculate each separately and sum the dry matter volumes for total storage needs.

Common Mistakes to Avoid

Forgetting to convert moisture percentage to a decimal (e.g., 15% should be 0.15) when calculating dry matter.
Using wet volume instead of dry matter volume, which overestimates storage space needed.
Mixing units, such as entering mass in kilograms but bulk density in lb/ft³, leading to incorrect volume results.
