Meat Cooking Temperature Calculator: Safe and Perfect Doneness Every Time
Find the correct internal temperature for beef, pork, poultry, fish, and lamb. Calculate cooking time by weight and know exactly when meat is safe to eat.
Cooking meat to the right internal temperature is the difference between juicy perfection and dry disappointment — and between safe and unsafe food. The USDA has specific guidelines, and the CalcHub Meat Cooking Temperature Calculator puts them all in one place along with estimated cooking times by weight and method.
USDA Safe Minimum Internal Temperatures
| Meat | Safe Minimum Temperature | Rest Time |
|---|---|---|
| Beef, pork, lamb (whole cuts) | 145°F (63°C) | 3 minutes |
| Ground beef, pork, lamb | 160°F (71°C) | None required |
| Poultry (all) | 165°F (74°C) | None required |
| Fish and shellfish | 145°F (63°C) | None required |
| Ham (fresh, uncooked) | 145°F (63°C) | 3 minutes |
| Ham (fully cooked, to reheat) | 140°F (60°C) | — |
| Eggs | 160°F (71°C) | — |
Beef Doneness Temperatures
Beyond "safe," beef is often cooked to preference:
| Doneness | Internal Temp | What It Looks Like |
|---|---|---|
| Rare | 120–125°F | Deep red center, cool |
| Medium-rare | 130–135°F | Warm red center |
| Medium | 140–145°F | Pink center throughout |
| Medium-well | 150–155°F | Slightly pink center |
| Well-done | 160°F+ | No pink |
Estimated Cooking Times by Weight
These are estimates — always verify with a thermometer.
Beef Roast (325°F oven)
| Weight | Rare (120°F) | Medium (145°F) | Well-done (165°F) |
|---|---|---|---|
| 3 lbs | 1 hr 15 min | 1 hr 45 min | 2 hrs 15 min |
| 5 lbs | 1 hr 45 min | 2 hrs 30 min | 3 hrs 15 min |
| 8 lbs | 2 hrs 30 min | 3 hrs 30 min | 4 hrs 30 min |
Whole Chicken (375°F oven)
| Weight | Time to 165°F |
|---|---|
| 4 lbs | 1 hr 20 min |
| 5 lbs | 1 hr 40 min |
| 7 lbs | 2 hrs 15 min |
The Rest Period
Resting meat after cooking serves two purposes: the internal temperature continues to rise 5–10°F (carryover cooking), and juices redistribute throughout the meat. Take the meat off heat when it's 5–10°F below your target temperature.
| Cut | Rest Time |
|---|---|
| Steak, chicken breast | 5 minutes |
| Pork chops, fish fillets | 3–5 minutes |
| Whole chicken | 10–15 minutes |
| Beef roast | 15–20 minutes |
| Large turkey | 30 minutes |
My thermometer shows 165°F in one part but 155°F in another. What do I do?
Cook until the coldest part reads 165°F. The thickest part of poultry — typically the innermost part of the thigh — takes longest. Insert the thermometer in multiple locations for large cuts.
Can I eat rare pork?
Yes — but only for whole cuts that have never been ground or mechanically tenderized. USDA lowered the safe temperature for whole-cut pork to 145°F in 2011. Ground pork still requires 160°F. Pink in a properly temperature-verified pork chop is now safe.
Does cooking method affect time estimates?
Yes significantly. The calculator covers oven roasting, grilling, smoking, sous vide, and stovetop methods with separate time estimates for each.
