Here are the official formulas: To convert Celsius to Fahrenheit: (degrees in celsius * 1.8) + 32. To convert Fahrenheit to Celsius: (degrees in Fahrenheight - 32) * 0.55.

When converting Celsius to Fahrenheit, the formula is: (°C * 1.8) + 32 = °F. You multiply 1.8 to the number of degrees Celsius, then add that number to 32.

The standard conversion formula which states; °F = (°C × 9/5) + 32, is mathematically correct but practically useless during timed exams. Multiplying by 9/5 means converting to decimals (1.8 ...

C to F: Multiply the temperature by 2 and then add 30 (actual formula is multiply by 1.8, add 32) ex: 22 C is roughly equal to 74 degrees using my method, actual conversion is 71.6 ...
