Uses [pint](https://github.com/hgrecco/pint) behind the scenes. Also contains a form field class and form widget that allows a user to choose alternative units to input data. The cleaned_data will output the value in the base_units defined for the field, eg: you specify you want to store a value in grams but will allow users to input either grams or ounces.\n\nCompatibility\n-------------\n\nRequires django >= 1.8, and python 2.7/3.2/3.3/3.4\n\nInstallation\n------------\n\n    pip install django-pint\n\n\nSimple Example\n-----------------------\nBest way to illustrate is with an example\n\n    # app/models.py\n    \n    from django.db import models\n    from quantityfield.fields import QuantityField\n    \n    class HayBale(models.Model):\n\t    weight = QuantityField('tonne')\n\nQuantities are stored and retrieved like any other field\n\n    >> bale = HayBale.objects.create(weight=1.2)\n    >> bale = HayBale.objects.first()\n\t>> bale.weight\n\t<Quantity(1.2, 'tonne')>\n\t>> bale.weight.magnitude\n\t1.2\n\t>> bale.weight.units\n\t'tonne'\n\t>> bale.weight.to('kilogram')\n\t<Quantity(1200, 'kilogram')>\n\t>> bale.weight.to('pound')\n\t<Quantity(2645.55, 'pound')>\n\nYou can also pass Quantity objects to be stored in models. These are automatically converted to the units defined for the field ( but can be converted to something else when retrieved of course ).\n\n    >> from quantityfield import ureg\n    >> Quantity = ureg.Quantity\n    >> pounds = Quantity(500 * ureg.pound)\n    >> bale = HayBale.objects.create(weight=pounds)\n    >> bale.weight\n    <Quantity(0.226796, 'tonne')>\n\nUse the inbuilt form field and widget to allow input of quantity values in different units\n\n    from quantityfield.fields import QuantityFormField\n\n    class HayBaleForm(forms.Form):\n        weight = QuantityFormField(base_units='gram', unit_choices=['gram', 'ounce', 'milligram'])\n\nThe form will render a float input and a select widget to choose the units. Whenever cleaned_data is presented from the above form the weight field value will be a Quantity with the units set to grams ( values are converted from the units input by the user ).\n\nFor comparative lookups, query values will be coerced into the correct units when comparing values, this means that comparing 1 ounce to 1 tonne should yield the correct results.\n\n    less_than_a_tonne = HayBale.objects.filter(weight__lt=Quantity(2000 * ureg.pound))",
