Boiling Point Calculator

Your details

Altitude mode: find the boiling point of water at a given elevation or pressure. Elevation mode: find how much a solute raises the boiling point of a solvent.
Elevation above sea level. Use negative values for below sea level (e.g., Dead Sea).

Boiling point: 100.0 °C at 1013 hPa

  • Water boils at 100.0 °C (212.0 °F) at 1013.2 hPa.

Next stepFor cooking at altitude, increase cooking time by roughly 10% for every 1,000 m (3,300 ft) above sea level.
