+## .unitFormatter( unit, options ) ➜ function( value )
+
+Returns a function that formats a unit according to the given unit, options, and the
+default/instance locale.
+
+The returned function is invoked with one argument: the number `value` to
+be formatted.
+
+### Parameters
+
+**unit**
+
+String value indicating the unit to be formatted. eg. "day", "week", "month", etc.
+Could also be a compound unit, eg. "mile-per-hour" or "mile/hour"
+
+**options**
+
+- form: [String] eg. "long", "short" or "narrow".
+
+- numberFormatter: [Function] a number formatter function. Defaults to Globalize
+  `.numberFormatter()` for the current locale using the default options.
+
+**value**
+
+The number to be formatted.
+
+### Example
+
+Prior to using any unit methods, you must load `cldr/main/{locale}/units.json` and the
+CLDR content required by the plural module. Read [CLDR content][] if you need
+more information.
+
+[CLDR content]: ../../../README.md#2-cldr-content
+
+You can use the static method `Globalize.unitFormatter()`, which uses the default
+locale.
+
+```javascript
+var customNumberFormatter, formatter;
+
+Globalize.locale( "en" );
+formatter = Globalize.unitFormatter( "month", { form: "long" } );
+
+formatter( 1 );
+// > "1 month"
+
+formatter( 3 );
+// > "3 months"
+
+formatter( 3000 );
+// > "3,000 months"
+```
+
+You can pass a custom number formatter to format the number of units.
+
+```javascript
+var customNumberFormatter, formatter;
+
+Globalize.locale( "en" );
+customNumberFormatter = Globalize.numberFormatter({ useGrouping = false })
+formatter = Globalize.unitFormatter( "mile-per-hour", {
+	form: "narrow", numberFormatter: customNumberFormatter
+} );
+
+formatter(5000)
+// > "5000mph"
+```
+
+You can use the instance method `.unitFormatter()`, which uses the instance locale.
+
+```javascript
+var globalize = new Globalize( "en" ),
+	formatter = globalize.unitFormatter( "mile-per-hour", { form: "narrow" } );
+
+formatter( 10 );
+// > "10mph"
+```
