Boiling Point of Water

Calculates the boiling temperature of water at a specified altitude under normal weather conditions. The lower the air pressure, the lower the boiling point, so the sooner the water starts to boil. At sea level it is at the well-known 100°C (degrees Celsius), on Mount Everest it is only around 70°C. The boiling point drops by about 0.003354°C (or Kelvin) per meter above sea level.
Enter one value, the other will be calculated.

Altitude above sea level : m
Boiling point: °C

Physics commonly uses SI units. Here is a calculator to convert lengths, temperature, pressure, speed and other units.
