Meat Cooking Time Calculator

Frequently Asked Questions

What is the safe internal temperature for meat?

USDA targets: poultry 165°F (74°C), ground meats 160°F (71°C), beef, pork, and lamb steaks 145°F (63°C) plus a 3-minute rest. Whole-muscle pork has also been 145°F since 2011.

How long per pound for roast beef?

At 325°F (160°C): about 20 min/lb for medium-rare and 25 min/lb for medium. Always use a thermometer, since shape and starting temperature affect this more than weight does.

Why does meat keep cooking after I take it out?

Carryover cooking. The internal temperature rises 5 to 10°F as residual heat conducts inward. Pull meat a few degrees below your target and let it rest 10 to 15 minutes.

Is the "10 minutes per inch" rule reliable for fish?

It is a rough guide for moderate-temperature roasting (around 400°F). Fish is done at 145°F (63°C) internal, when the flesh flakes. Thin fillets cook in 6 to 8 minutes total.

How This Calculator Works

Pick the type of meat, enter its weight, and choose your oven temperature. The calculator estimates total roasting time from standard minutes-per-pound guidelines used by the USDA and culinary schools, and shows the minimum safe internal temperature for that cut. It also surfaces a doneness note: rare to well-done targets for beef, resting guidance for poultry, and reheat notes for ham. Weight can be entered in pounds or kilograms; kilograms are converted to pounds before the time is computed.

Formula

Cook time in minutes = minutes per pound × weight in pounds × temperature factor. If you enter kilograms, the tool first converts: lb = kg × 2.20462. Minutes-per-pound values are calibrated to 325°F; the temperature factor scales them for other oven settings (1.25 at 275°F, 0.90 at 350°F, 0.75 at 400°F, and so on). The safe internal temperature shown is independent of oven temperature and follows USDA targets (165°F for poultry, 145°F for whole-muscle beef, pork, and lamb).

Common Mistakes

Trusting time over temperature: always confirm doneness with a meat thermometer.

Skipping the rest. Carryover cooking adds 5 to 10°F, so pull the roast a few degrees early.

Roasting straight from the fridge. Cold meat takes 20 to 30% longer than room-temperature meat.

Ignoring shape. A thick, compact roast cooks slower than a thin one of equal weight.

Assuming the oven dial is accurate. Many home ovens run 25 to 50°F off; use an oven thermometer.

Tips and FAQ

What temperatures are safe? Poultry 165°F, whole beef, pork, and lamb 145°F (with a 3-minute rest), ground meat 160°F, fish 145°F. Why rest the meat? Resting lets fibers relax and reabsorb juices, giving a juicier slice. Does bone-in change the time? Bone conducts heat near it, but the thickest meat away from the bone still governs total time. Can I cook from frozen? Not recommended for whole roasts; thaw fully for even, safe cooking.
