## Prompt

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

## Response

The boiling point of water at sea level (standard atmospheric pressure of 1 atm or 101.325 kPa) is exactly 100°C or 212°F.

This value is defined under the International System of Units and confirmed by physics standards for pure water.

**Key details**  
- Applies to pure water at 1 atm pressure.  
- Varies with altitude, impurities, or pressure changes.

What factors beyond pressure might affect water's boiling point in everyday scenarios?
