About Pressure Cooker Calculator
The Pressure Cooker Calculator solves 1/T₂ = 1/373 − R·ln(P₂/P₁)/ΔH_vap for you with the full working shown — every substitution, every unit, every step, exactly the way a good teacher writes it on the board. At 2 atm a standard pressure cooker boils water at ~121 °C — and since reaction rates roughly double per 10 °C, dal cooks 4× faster with a whistle than without.

Frequently asked questions
What formula does the Pressure Cooker Calculator use?+
It uses 1/T₂ = 1/373 − R·ln(P₂/P₁)/ΔH_vap. The steps section shows the formula with your actual numbers substituted, so you can follow (and verify) every stage of the calculation rather than trusting a black box.
What should I keep in mind when using this calculator?+
At 2 atm a standard pressure cooker boils water at ~121 °C — and since reaction rates roughly double per 10 °C, dal cooks 4× faster with a whistle than without. The same maths runs in reverse on mountains, and at 121 °C it doubles as sterilisation: that's exactly an autoclave.
Is the Pressure Cooker Calculator free to use?+
Completely free, with no sign-up or limits. All computation happens client-side in your browser, so it is fast, private, and works even on slow connections once the page has loaded.
Can I use this for homework, teaching or exam prep?+
That is exactly what it is built for. The step-by-step working mirrors how solutions are presented in class, so you can check homework, build worked examples for teaching, or practise method recall before exams.
