Office Cooking Time Calculator — How It Works

Estimates total cooking time based on food weight and cooking rate.

How it works

  1. Enter the weight of the food, in kilograms.
  2. Enter the cooking time per kilogram, in minutes (this varies by food and method).
  3. Enter any base or preheat time.
  4. The tool multiplies weight by the per-kilogram rate, adds the base time, and converts the result into hours and minutes.

Formula

Total time (minutes) = Base time + (Food weight (kg) × Minutes per kg)

Example

A 2 kg roast at 40 minutes per kg, plus 20 minutes base time, takes about 1 hour 40 minutes (100 minutes) total.

Notes

Cooking times per kilogram vary widely by food type, cut, oven temperature, and whether the food is fresh or frozen. Always verify doneness with a food thermometer for meat and poultry rather than relying on time alone.
