What affects actual cooking time

Weight is only one part of the estimate. The food and oven can change the actual time.

Shape and thickness

A compact piece takes longer than a flatter one, even when both weigh the same.

Bones and filling

Bones, filling and the starting temperature can slow heating at the center of the food.

Oven and cookware

Every oven heats differently. Use the estimate as a reminder to measure, not as a guarantee.

Frequently asked questions

How do you calculate cooking time by weight?

Multiply the weight by the minutes per kilogram or pound, add any extra cooking minutes, and then add resting time to estimate when the food will be ready to serve.

Does the estimated time confirm that the food is safe?

No. Time only helps you plan. Confirm safe cooking by measuring the internal temperature with a food thermometer.

Why does the calculator show a range?

Two pieces with the same weight can cook differently because of their thickness, shape, bones, filling, starting temperature, oven and cookware.

Can I use my own minutes-per-weight rate?

Yes. Switch to manual mode and enter the rate from your recipe, package directions or experience. The calculator converts between kilograms and pounds when needed.

What does start checking mean?

It is the time calculated from the lower end of the range. Start measuring the internal temperature then and decide whether the food needs more time.

Is resting time included in cooking time?

It does not change the estimated finish time. It is added afterward to estimate when the food will be ready to serve.
