Quizplus · Accepted Answer

The Celsius and Fahrenheit scales coincide at -40°. At this temperature, -40° Celsius is equal to -40° Fahrenheit. They do not coincide at 0°, as 0° Celsius is equal to 32° Fahrenheit. Additionally, they do not coincide at 212° Fahrenheit, as this is equivalent to 100° Celsius. The Celsius scale has its zero point at the freezing point of water (0° Celsius), while the Fahrenheit scale has its zero point at the theoretical temperature at which all molecular motion would cease (-459.67°F or -273.15°C), also known as absolute zero.
