Sometimes you just want to convert from one unit to another.

unit = require('unitology')
unit.time('5m').to('s') // -> 300
unit.length('5m').to('inches') // -> 196.85
unit.weight('5kg').to('pounds') -> 11.0231

Well, you get the idea. But what about custom conversions?

unit.time.fortnight = '2 weeks'
unit.time('1 year').to('fortnight') // -> 26.0887285
unit.time('2 fortnights').to('days') // -> 28

Okay, so you can add a new unit to an existing type of measurement. What about totally new measures?

unit.volume = unit.define('l')
unit.volume.liter = 'l'
unit.volume.litre = 'l'
unit.volume.cc = '0.001l'
unit.volume.define({ 'cubic meters': '1000l', 'm3': 'cubic meters' })

TBD

Though it might be nicer, and more concise, to write this way:

unit.volume = unit.define(
  'l, liter, litre',
  {
    cc: '0.001l',
    'cubic meters, m3': '1000l'
  }
)

Also: How to convert units like temperature? More complex formula needed.

Maybe:

unit.temp['K->C'] = function(k) { return k + 273 }
unit.temp['C->K'] = function(c) { return c - 273 }

Or something?
