212F = 100C = boiling point at standard temp and pressure.
So from F to C first subtract the 32 degrees difference at freezing, then multiply the ratio of C:F which would be 100:180.
So 212-32=180F
And 100/180 is 5/9
So 180F x 5/9 = 100C
Remember: (F-32) x 5/9 = C
the opposite: (C x 9/5) + 32 = F

To convert from Fahrenheit to Celsius do the following: (Temp F - 32) * 5 / 9 = Temp C To convert from Celsius to Fahrenheit do the opposite: Temp C * 9 / 5 + 32 = Temp F This is easy to remember using the boiling point of water (100 C or 212 F). (212 F - 32) * 5 / 9 = 100 C 100 C * 9 / 5 + 32 = 212 F
212°F is 100°C
Use this equation to convert degrees Fahrenheit (ºF) to degrees Celsius/Centigrade (ºC): [°C] = ([°F] − 32) × 5⁄9
100 C is 212 F
0 C = 32 F 100 C = 212 F 180 degrees F equals the measurement of 100 degrees C 9 degrees F therefore equals 5 degrees C -40 F is 72 degrees F below freezing -40 C is 40 degrees C below freezing Convert F to C 5 times -72 is -360 divided by 9 is -40 C convert C to F 9 times -40 is -360 divided by 5 is -40 F
