Formula
Simple estimate uses about 3,500 kcal per pound; real outcomes vary with physiology and behavior.
Understanding the Results
The primary answer appears first. Supporting outputs show related quantities, conversions, dates, costs, ratios, or intermediate values. Calculations keep additional precision before display rounding.
Accuracy Tips
- Use measured values and consistent units.
- Review assumptions, waste rates, fees, timing, and efficiency inputs.
- Recalculate after changing any project condition.
