The boiling temperature of water is 100 degrees Celsius (°C) and 212 degrees Fahrenheit (°F). This is the point at which water changes from a liquid to a gas under standard atmospheric pressure. The Celsius scale is based on the freezing and boiling points of water, with 0°C being the freezing point and 100°C the boiling point. The Fahrenheit scale, on the other hand, sets the freezing point of water at 32°F and the boiling point at 212°F. The difference between the two scales is due to their different starting points and the size of their degrees.
