Temperature scales

• Celsius
• Definition
• freezing point of water is defined to be 0°C and boiling point of water is defined to be

100°C (at 1 atm pressure), a 100°C separation.

• Fahrenheit
• Definition
• freezing point of water is defined to be 32°F and boiling point of water is defined to be

212°F (at 1 atm pressure), a 180°F separation.

• Scale conversion (Fahrenheit to Celsius)
• F2C:
• Absolute zero
• The lowest limit of the thermodynamic temperature scale.
• -273°C (approximation)

F2C Converter

• Basic function
• input: the temperature expressed in Fahrenheit scale
• output: converted temperature in Celsius scale
• Restriction
• Your program must print a prompt message to tell the user as entering a

Fahrenheit scale temperature.

• The printed result must have two or more significant digits below the decimal
• point. (소수점 아래 2개 이상의 유효 숫자)
• If converted value(in Celsius) is smaller than the absolute zero(-273°C), your

program must tell the input is invalid and ask user a new input value. This process should be repeated until the input value is converted in the valid range(≥ -273°C).

• Submission
• You should make a ‘f2c’ subdirectory in your home directory.
• Only your C source code and compiled execution file must be in the ‘f2c’

directory.
