  • Age: 10 weeks
  • Breed Factor: 6 (medium)

Calculation: The calculator uses a simple formula: Adult Weight=Current WeightAge in Weeks×Breed Factor×52\text{Adult Weight} = \frac{\text{Current Weight}}{\text{Age in Weeks}} \times \text{Breed Factor} \times 52Adult Weight=Age in WeeksCurrent Weight​×Breed Factor×52

  • Plugging in the numbers:

810×6×52=249.6 lbs (estimated adult weight)\frac{8}{10} \times 6 \times 52 = 249.6 \text{ lbs (estimated adult weight)}108​×6×52=249.6 lbs (estimated adult weight)
