My union raised the rate by ₹10 a kg of fat. What is that on a litre?
At FAT 6.5, ₹0.65 a kg of milk and about ₹0.67 a litre. On 1,000 litres that is about ₹670 a day.

The sum
FAT rate: from a kg of fat to a litre of milk
FAT 6.5 means 6.5 kg of fat in 100 kg of milk. So one kg of milk holds 0.065 kg of fat, and 0.065 × ₹800 = ₹52.00.
A litre of milk weighs more than a kg, about 1.03 kg. So ₹52.00 × 1.03 = ₹53.56. ₹800 is an example, not any union's rate.

₹800 a kg of fat at five FAT readings
The common slip is to stop at the kg figure and call it a litre rate. At FAT 6.5 that leaves out ₹1.56 on every litre, which is ₹1,560 on 1,000 litres.
| FAT | A kg of milk | A litre | 1,000 litres |
|---|---|---|---|
| 4.0 | ₹32.00 | ₹32.96 | ₹32,960 |
| 5.0 | ₹40.00 | ₹41.20 | ₹41,200 |
| 6.0 | ₹48.00 | ₹49.44 | ₹49,440 |
| 6.5 | ₹52.00 | ₹53.56 | ₹53,560 |
| 7.0 | ₹56.00 | ₹57.68 | ₹57,680 |
₹800 is an example rate, and a litre is taken as 1.03 kg, as in the tool. This counts fat alone.
Why multiply by 1.03?
Because a litre of milk weighs about 1.03 kg, so a litre is worth a little more than a kg. Milk density explains why.
A litre weighs 1.03 kgMy plant pays by the kg, not the litre. What do I use?
Stop at the A kg of milk line. That is your rate, and the 1.03 step does not apply.
The kg lineMy union pays for SNF too. Does this cover it?
No. This tool counts fat alone. If your plant has a rate a kg of SNF as well, work that part the same way with your SNF and add it on.
