Boiling Point vs Altitude

Approximate drop in water's boiling point with elevation (h in metres).

Formula

Tb100h285T_b \approx 100 - \frac{h}{285}

Variables

T_bBoiling point (°C)
hAltitude (m)

Example

1500 m: T_b ≈ 100 - 5.3 = 94.7°C

Did You Know?

In high-altitude cities like Denver, water boils around 95°C, so pasta and eggs take noticeably longer.
