Degrees Celsius to hectopascals
Type a value in °C to get it in hPa instantly.
123.1hPa
At 50 °C water’s vapor pressure is 12.31 kPa (1.785 psi): water boils at that temperature when the pressure is that low.
What it means
How hot is that?
Antoine equation for pure water, 1 to 374 °C (two sets of constants); within about 0.5 % of steam tables.
The math
How to convert °C to hPa
log₁₀ p(mmHg) = 8.07131 − 1730.63 ÷ (233.426 + T) for 1–100 °C; above, A = 8.14019, B = 1810.94, C = 244.485.
Example: 50 °C = 123.056 hPa.
