Meat Roasting Time Calculator
Calculate roasting time and target internal temperature by joint weight and doneness.
What this page needs from you
This page asks for joint weight in kg and meat. From those it returns roasting time in min, together with in hours, minutes per kg, resting time and target internal temp. Every figure updates as you type, and nothing you enter leaves your browser.
When to use something else
Every calculation is a model, and a model is a deliberate simplification. Where the answer will drive a decision that is expensive or hard to reverse, use this to understand the shape of the problem and then confirm the specifics with someone who can see details this page cannot.
Reading the result properly
The figure above answers exactly the question the inputs describe and no more. Changing one input at a time and watching which part of the breakdown moves usually teaches more than the headline number does, because it shows which variable your situation is actually sensitive to.
The formula
Time = minutes per kg × weight + 20 minutes, at 180 °C
Every result on this page comes from this formula. Nothing is rounded until the final display, so figures match a spreadsheet to the cent.
