Boneless Meat (kg) to Live Weight (kg)
Bought bulk freezer lamb and curious how big the animal was on the hoof? This tool reverse-engineers the 35% boneless yield rule. Input the final weight of the consumable meat (kg) to instantly calculate the estimated live weight (kg). The multiplier is 2.857.

The Mathematics of Total Reversal
When projecting forward from a live animal, we multiply by 0.35 because the final boneless meat is roughly 35% of the starting weight. To calculate backward from the final meat box to the live animal, we divide by 0.35, which creates the 2.857 multiplier.
Where did the rest go?
- 50%: Lost immediately at slaughter (blood, hide, head, hooves, internal organs).
- 15%: Lost during butchery (bones, cartilage, and heavy fat trimming).
- 35%: The pure meat that reaches the freezer.
The Formula
Meat kg × 2.857
= Live kg
