### Temperature

I just felt like explaining some Basic formulas. For people who know fractions, and wonder, here are some temperature conversions:

Fahrenheit to Celsius is   5/9 of (F-32)   Or (F-32)x5/9

Celsius to Fahrenheit is  9/5 of (C+32)  Or (C+32)x9/5

Celsius to Kelvin is C+273

Celsius to Rankine is C+273.15 x 9/5

Celsius to Delisle is 100-C x 3/2

Celsius to Newton is C x 33/100

Celsius to Réaumur is C x 4/5

Celsius to Rømer is C x 21/40 + 7.5

((C=Celsius))

Okay, there you go!

MATH......that is all.

### Re: Temperature

Celsius to Fahrenheit is not 9/5 of (C+32)  Nor (C+32)x9/5.

It is (9/5 of C)+32.

For example 0C is 32F, as the most obvious example. 9/5 of (0C+32) is not equal to 32F, but (9/5 of 0C)+32 is equal to 32F. The formual (9/5 of C)+32 also works on other perhaps obvious examples, like 100C is 212F and -40C is -40F.

### Re: Temperature

What countries do they come from and what are Rankine, Delisle, Reaumur and Romer? I know of the rest... they are used in chemistry...

By the power of the exponent, I square and cube you!
