**Enter a number in either
the F or C fields, then click outside

The formula for:

C to F is: C * 9, then divide by 5 and then + 32...

or

9
(212-32)

F = C x ---- +32 or
C x ------------ + 32

5
100

**And to really make it simple for everybody who doesn't tend
to remember math equations?**

F =
C x 1.8 + 32 |

and for F to C?"Flip" the equation and reverse the calculation order |

C =
F - 32 / 1.8 |

**Using only the 2 factors, "1.8" and "32" reduces
potential equation error**

**If you are doing it right, the boiling
point of water at STD barometric pressure, 100c will always convert to 212f and
212f will always convert to 100c.**

For some background, to make it easier (or harder :-) to remember, the C to F formula is really:

**C * (212-32)** (it's always **180** and that's where your Lowest
Common Denominator "9" comes from), then, **divide by 100** (there's where
your Lowest Common Denominator "5" comes from), then, **+ 32**. =**
F**
