## Prompt

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

## Response

At standard atmospheric pressure at sea level, water boils at **100°C (212°F)**. Scientifically precise measurements place the boiling point at 99.97 °C (211.95 °F) under standard pressure at sea level [Wikipedia Water Data Page](https://en.wikipedia.org/wiki/Water_(data_page)). For most practical purposes, the round figures of 100 °C and 212 °F are used.

These values assume a standard atmospheric pressure of 101.325 kPa (1 atm). The boiling point decreases as elevation increases because atmospheric pressure drops — at 1,000 meters above sea level, water boils at approximately 96.7 °C (206.6 °F), and at 2,000 meters it drops to about 93.4 °C (201.1 °F) [Wikipedia Water Data Page](https://en.wikipedia.org/wiki/Water_(data_page)).
