What is the boiling point of water?

212 Fahrenheit or 100 Celsius.
The boiling point of water is 100°C, 212°F or 373.15 Kelvin under standard conditions at sea level (at one atmosphere of pressure).
The boiling point of water and any other substance depends on the atmospheric pressure, which changes with elevation. At higher altitudes, the pressure is lower, and so water boils at a lower temperature. If the barometric pressure is not at the standard value, the boiling point will be different. For example, water boils at 72 degrees Celsius on Mount Everest.
Under a partial vacuum water boils at room temperature. In space (a full vacuum) water goes directly from solid ice to gas without even melting or boiling, this is called sublimation.
Water boils at 212 degrees Fahrenheit and 100 degrees Celsius.
The above answer is correct, provided you are at sea level. The higher you go the lower the temprature is needed to reach boiling. Getting a bit more technical, it also depends on the purity of the water you are boiling. Best we got in height school was around 97 degrees Celsius.
