how do i change grades Centigrade for Fahrenheit?

Answer 1

Add 40, double it, subtract a tenth, subtract 40.

80 Centigrade -> 120 -> 240 -> 216 -> 176 Fahrenheit.

Answer 2

The equations above are correct.

If you don't want to do any math though, Google has incorporated a very handy conversion calculator into their search engine.

What you actually want to do is "convert between degrees Celsius (C) and degrees Fahrenheit (F)" This is important because if you want to find the answer to a question yourself, you have to first know what you are really looking for.


Open up www.google.com and just type what you want to convert. The line below is an example..

Convert 75 degrees C to F

The answer will be in big bold letters at the top of your search results. You can do the same thing with many common unit conversions. Even if google doesn't do the math for you, the search results will almost always give you the equation you will need and often step-by-step instructions.

Answer 3

F = 9/5C + 32; C = 5/9(F-32). In the first formula, you add the 32 degrees after you calculate 9/5*C (or 1.8*C). In the second formula, subtract the 32 degrees from F before you multiply by 5/9 (or 0.555...).

Answer 4

F = 1.8C + 32

for example,

the temperature of boiling water is 100 deg C.

F = 1.8(100) + 32

F = 180 + 32

F = 212 deg F
