Celsius The Metric Temperature Scale Also called the centigrade scale. Definitions 0°Celsius(C) = 32°Fahrenheit(F) = water freezes 100°Celsius = 212°Fahrenheit = water boils Conversions °Celsius = 5/9 X (°Fahrenheit - 32°) °Fahrenheit = (9/5 X °Celsius) + 32° 30 is hot, 20 is nice, 10 is chilly, 0 is ice.
