About this calculator
This multiplies the entered weight in kilograms by your chosen minutes-per-kilogram rate, then adds resting time. It does not identify the food or estimate a safe internal temperature; cooking time varies with shape, starting temperature and equipment. Use a food thermometer and follow current food-safety guidance.
Worked example
calculated with the default values below
Weight (kg) 2 kg · Cooking time per kg 45 min/kg · Resting time 20 min Cooking time 90 min · Cooking time 1.50 h · Total including rest 110 min · Equivalent per pound 20.4 min/lb
General background references
Disclaimer
These calculators give general cooking guidance. Ingredient density, oven calibration, altitude and equipment all vary, and safe minimum internal temperatures always take precedence over timings. Follow the food-safety advice issued by your national authority.

This record describes the implementation used by this page. It is not independent validation. External references, when available, support only the stated formula or definition; estimates and custom rules retain their own assumptions.
Formula and variables
T = w × m; m_lb = m ÷ 2.2046226218; T_total = T + r
- w
- weight in kg
- m
- minutes per kg
- T
- cooking minutes
- r
- resting minutes
- m_lb
- minutes per pound
- T_total
- total minutes
Uses the user-entered cooking rate in minutes per kilogram and the entered weight in kilograms; times are estimates and food safety depends on internal temperature.
