At what temperature are the Celsius and Fahrenheit scales the same?
Fahrenheit is a temperature scale that bases the boiling point of water at 212° and the freezing point at 32°. It was developed by Daniel Gabriel Fahrenheit, a German-born scientist who lived and worked primarily in the Netherlands.
Today, the scale is only used in the United States and few Caribbean countries. The rest of the world uses the Celsius scale, where water freezes at zero degrees and boils at 100 degrees. The Fahrenheit and Celsius scales converge at minus 40°F, so that minus 40°F and minus 40°C represent the same temperature.
Answer: The correct answer is -40°
