## Prompt

What is the boiling point of water at sea level, in both Celsius and Fahrenheit? Cite a source.

## Response

Water boils at **100 °C (212 °F)** at sea level under standard atmospheric pressure (1 atm, 101.325 kPa). With scientific precision, the normal boiling point is actually 99.97 °C (211.95 °F) [Wikipedia](https://en.wikipedia.org/wiki/Boiling_point?wprov=sfla1).

A few refinements worth knowing:

- The IUPAC-recommended standard boiling point, defined at a slightly lower pressure of 100 kPa (1 bar), is 99.61 °C (211.3 °F) [Wikipedia](https://en.wikipedia.org/wiki/Boiling_point?wprov=sfla1).
- The familiar 100 °C figure is a historical convention; the Celsius scale was defined until 1954 by water's freezing point (0 °C) and boiling point (100 °C) at standard atmospheric pressure [Wikipedia](https://en.wikipedia.org/wiki/Boiling_point?wprov=sfla1).
- Boiling point drops with altitude — for example, water boils at about 93.4 °C at 1,905 m elevation and just 71 °C atop Mount Everest [Wikipedia](https://en.wikipedia.org/wiki/Boiling_point?wprov=sfla1).

Would you like a table of water's boiling point at different elevations or pressures?
