What

Temperature makes it easy to deal with temperatures in Ruby, but
adding mixin methods to numbers and strings.

This was inspired by using Ruby to manipulate data from my home
weather station, and wanting it to keep track of the units for me so
that I didn’t have to think about that in code.

Installing

sudo gem install temperature

Demonstration of usage

freezing_in_F = 32
freezing_in_C = freezing_in_F.to_C

boiling_in_C = 100
boiling_in_C.units = "C"
boiling_in_F = boiling_in_C.to_F

absolute_zero = "0K".to_degrees
absolute_zero_in_C = absolute_zero.to_C
absolute_zero_in_F = absolute_zero.to_F

There is also support to calculate dewpoint from relative humidity
based on the NOAA approximation documented here -
http://en.wikipedia.org/wiki/Dew_point#Closer_approximation

dewpoint = 32.dewpoint(45)
