Celsius <-> Fahrenheit in PowerShell

[Tuxman]

I had a request to myself: I want to convert Fahrenheit <-> Celsius on Windows without having to install a whole bunch of GNU utilities (which would have been the easiest way, I presume). So I wrote a converter for Powershell which I use anyway.

Code: PowerShell [Select]

1. function FtoC([double]$fahrenheit) {
2.         $celsius = ($fahrenheit - 32) * (5/9)
3.         "{0} °F = {1} °C" -f $fahrenheit,[math]::Round($celsius,3)
4. }
5.  
6. function CtoF([double]$celsius) {
7.         $fahrenheit = ($celsius * (9/5)) + 32
8.         "{0} °C = {1} °F" -f $celsius,[math]::Round($fahrenheit,3)
9. }

Usage:

[Select]

> FtoC(32)
32 °F = 0 °C
> CtoF(0)
0 °C = 32 °F
