Kelvin

A small library for handling temperatures.

It's as precise as a 64 bit Float.

Installation

Add this to your application's shard.yml:

dependencies:
  kelvin:
    github: tijn/kelvin

Usage

require "kelvin"

temperature = Kelvin::Temperature.celcius(22.3)
puts temperature
# => "22.3 °C" : String
# or if you're in the US, it will output: "72.1 °F" : String
# It follows the LOCALE settings on your system.

puts temperature.to_kelvin
# => 295.45

It can also parse text:

require "kelvin"

temperature = Kelvin::Temperature.parse("22.3 °C")
puts temperature
# => "22.3 °C" : String

and you can use it to compare temperatures on different scales.

temperature_in_paris = Kelvin::Temperature.parse("22.3 °C")
temperature_in_boston = Kelvin::Temperature.parse("70.1 °F")

city = (temperature_in_paris > temperature_in_boston) ? "Paris" : "Boston"
puts "#{city} is warmer today"
