Pork joint Cooking Time Calculator — Time, Temperature & Method

Pork joint Cooking Time Chart

Weight	Cooking time	Internal temp
3 lb	1 hr 52 min	160°F
4 lb	2 hr 19 min	160°F
5 lb	2 hr 46 min	160°F
6 lb	3 hr 13 min	160°F

🌡️ Stop guessing — check the real temperature

A fast digital meat thermometer is the only way to know your roast is safely and perfectly cooked. Pull it at the exact internal temperature, every time.

How This Calculator Works — Formula & Method

Source: standard US roasting guidance · applied deterministically · verify with a thermometer

Constant	Value	Source
Time per lb	27 min/lb (range 30–35/500 g)	US roasting guides
Internal target	160°F / 71°C	USDA / thermometer
Base offset	30 min	Standard
Oven	430°F sear for 25 min, then 350°F	Method
Resting	15 min	Best practice

— Pork joint cooking time —
total_min = min_per_500g × (weight_lb × 453.592 / 500) + base_offset
range = [lo_per_500g … hi_per_500g] × (weight / 500) + base_offset
conventional_oven = fan_temp + 10–20°C (same time)
celsius = derived table from °F
— algorithm —
lookup(meat, cut, doneness) → point_estimate → guidance_range
→ internal_target_temp → verify_with_thermometer()

Public roasting guidance applied deterministically — this is not a food-safety authority. Always cook to the stated internal temperature, measured with a meat thermometer.
