Inclusion rate converter: % ⇄ kg/tonne ⇄ g/tonne
Convert feed inclusion rates between percent, kg per tonne, g per tonne and ppm, and scale to any batch size. Formula, worked examples and mixing checks.
Short answer · reviewed August 2026
To convert a feed inclusion rate from percent to kg per tonne, multiply the percentage by 10: 1% = 10 kg/tonne. For micro-ingredients, 1 kg/tonne = 1,000 g/tonne = 1,000 ppm. To scale to a mixer batch, multiply kg/tonne by the batch size in tonnes — a 0.05% additive is 0.5 kg/tonne, or 250 g in a 500 kg batch.

Formula
kg per tonne = Inclusion % × 10 Inclusion % = kg per tonne ÷ 10 g per tonne = Inclusion % × 10,000 (= ppm) Batch quantity (kg) = kg per tonne × Batch size (tonnes)
Micro-ingredients below roughly 0.5 kg/tonne should be pre-mixed on a carrier before entering the main mixer to reach an acceptable coefficient of variation.
Worked examples
| Input | Calculation | Result |
|---|---|---|
| Soybean meal at 22% inclusion, 8-tonne batch | 22 × 10 = 220 kg/t; 220 × 8 | 1,760 kg per batch |
| Limestone at 1.2% inclusion | 1.2 × 10 | 12 kg per tonne |
| Phytase premix at 0.01% | 0.01 × 10,000 | 100 g per tonne (100 ppm) |
| DL-methionine at 0.25%, 500 kg batch | 0.25 × 10 = 2.5 kg/t; 2.5 × 0.5 | 1.25 kg per batch |
FAQ
How many kg per tonne is 1% inclusion?
1% inclusion equals 10 kg per tonne of finished feed, because one tonne is 1,000 kg and 1% of 1,000 kg is 10 kg.
Is 1 kg per tonne the same as 1,000 ppm?
Yes. 1 kg per tonne is 1,000 g per 1,000,000 g of feed, which is 1,000 parts per million.
How do I scale an inclusion rate to my mixer batch?
Multiply the kg-per-tonne figure by the batch size in tonnes. A 3 kg/tonne additive in a 2.5-tonne mixer is 7.5 kg per batch.
When should an additive go through a premix instead of direct dosing?
As a rule of thumb, anything dosed below about 0.5 kg per tonne should be carried in a premix so it distributes evenly and stays within mixing uniformity limits.
