That means our approximate formulas are: Celsius to Fahrenheit: double it and add 32. Fahrenheit to Celsius: subtract 32 and then cut the resulting number in half.

Instead of memorising complex formulas, smart students use approximation methods that deliver results fast enough for any testing situation. From Celsius to Fahrenheit: Double the Celsius number and ...

The formula for converting Celsius to Fahrenheit is like this chocolate bar. You take the Celsius temperature and make it 1.8 times bigger, then you add 32 to it.

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 formula to convert between the two temperature scales isn’t something most of us can do in our head, but if you just need a close estimation, quaxon’s formula works well: C to F: Multiply ...

When it comes to Fahrenheit vs. Celsius, the world is in agreement—mostly. Here's why the United States is still stuck on Fahrenheit.

For example, while 32 degrees Fahrenheit = 0 degrees Celsius, 35 degrees Fahrenheit = 1.6 degrees Celsius, which would likely be rounded up to 2°C to avoid having to use decimals.
