200 degrees Celsius is equal to 392 degrees Fahrenheit. There is an easily memorable formula for Celsius to Fahrenheit conversions: simply multiply the original figure by 9, divide by 5 and add 32. To convert the other way, just reverse the equation by subtracting 32, multiplying by 5 and dividing by 9.
This formula is especially useful in the United States, where Fahrenheit remains the standard unit of temperature despite scientists favoring Celsius for its practical utility. Formerly known as centigrade, Celsius was originally based on the freezing point (0 degrees Celsius) and boiling point (100 degrees Celsius) of water, and degrees Celsius are also the same size as degrees Kelvin, another commonly used unit of temperature in science.
