## Prompt

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

## Response

At sea level, water boils at **100 °C** and **212 °F**. NIST lists water’s boiling point as 100 °C / 212 °F, and also notes that this is the boiling point at sea level and standard atmospheric pressure. ([nist.gov](https://www.nist.gov/pml/owm/si-units-temperature?utm_source=openai))

Would you like the boiling point explained in terms of atmospheric pressure too?
