Question: what is the difference between the fahrenheit and celsius temperature scales?
Answer: On the Fahrenheit scale, water freezes at 32°F and boils at 212°F (at sea level). The Celsius temperature scale—originally called centigrade and later renamed for Swedish astronomer Anders Celsius—is used almost everywhere else in the world. On the Celsius scale, water freezes at 0°C and boils at 100°C (at sea level).
