SUMMARY

The discussion focuses on deriving temperature conversion formulas between Fahrenheit and Celsius. The formula for converting Fahrenheit (F) to Celsius (C) is established as C = 5/9(F - 32). The key steps involve recognizing the freezing point of water at 32°F and the boiling point at 212°F, leading to the conclusion that the temperature difference between these points is 180°F, which corresponds to a 100°C difference. This establishes the ratio of 5/9 for the conversion.

PREREQUISITES
  • Understanding of basic algebraic manipulation

Homework Statement



the fahrenheit temp scale is defined to that ice melts at 32 F and water boils at 212 F. Derive formulas for converting fahrenheit to celsius and back.

Homework Equations


c=5/9(f-32)

The Attempt at a Solution


ok so i figured that 212-32= 180
and
100-0=100
so the ratio of c/f= 5/9
i don't know how to get the 32 part into the equation

0C=32F. So a fahrenheit temperature f is (f-32) fahrenheit degrees above 0C. Now just convert the (f-32) fahrenheit degrees to celsius degrees.
