The formula gets rearranged depending on which variable you need. Here are the patterns you’ll run into in the real world — find the one that matches your problem and follow the worked steps.

01 · PATTERN

Dog weight (lb) halved

lbs = 20 (from 40)

Keep every other input at its default and halve the dog weight (lb). See how cups/day responds.

  1. 01New Dog weight (lb): 20
  2. 02Baseline Cups/day: 2.5
  3. 03New Cups/day: 1.5
  4. 04Cups/day decreases by 40% → use this sensitivity to plan for real-world variation.
02 · PATTERN

Dog weight (lb) doubled

lbs = 80 (from 40)

Keep every other input at its default and double the dog weight (lb). See how cups/day responds.

  1. 01New Dog weight (lb): 80
  2. 02Baseline Cups/day: 2.5
  3. 03New Cups/day: 4.5
  4. 04Cups/day increases by 80% → use this sensitivity to plan for real-world variation.
