Work out pressure cooker time instantly with clear inputs, formula shown and shareable results.
A pressure cooker runs at about 120 C, cutting time by roughly a factor of three, and the standard altitude rule adds 5% more time for every 300 m of elevation. At altitude water boils below 100 C so even a sealed cooker reaches a lower temperature, which is why high-altitude recipes need the extra allowance.
Base time
pressure minutes = conventional minutes / speed-up factor
Altitude allowance
add 5% per 300 m of elevation above sea level
