## Prompt

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

## Response

The boiling point of pure water at sea level (standard atmospheric pressure of 1 atm) is exactly 100°C, equivalent to 212°F.[[1]](http://www.fsis.usda.gov/food-safety/safe-food-handling-and-preparation/food-safety-basics/high-altitude-cooking)

This value holds under standard conditions for pure water without impurities or dissolved gases.

What factors can alter this boiling point in everyday scenarios?
