About this calculator
This provides a rough starting-point conversion using fixed time ratios for the selected source method. Recipes, appliance models, portion size and food safety requirements vary. Follow the slow cooker and recipe instructions; verify doneness with a food thermometer where needed.
Worked example
calculated with the default values below
Original cooking time 1 h · Original method Oven Approximate time on low 4.0 h · Approximate time on high 2.0 h
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.
Implementation source
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
b = h×m; T_low = 2b; T_high = b; M = 0.6V
- h
- Original recipe time (h)
- m
- Source multiplier
- b
- High-setting time (h)
- T_low
- Low-setting time (h)
- T_high
- Cooking time on high (h)
- V
- Cooker capacity (L)
- M
- Max batch size (kg)
Fixed time multipliers convert the source-method time into rough low/high estimates; ingredients, appliance variation, food quantity and safe doneness are not modeled.
