 You can add your own units to Math.js using the `math.createUnit` function. The following example defines a new unit `furlong`, then uses the user-defined unit in a calculation:
 
 ```js
-math.createUnit('furlong', '220 yards') 
+math.createUnit('furlong', '220 yards')
 math.evaluate('1 mile to furlong')            // 8 furlong
 ```
 
 If you cannot express the new unit in terms of any existing unit, then the second argument can be omitted. In this case, a new *base unit* is created:
 
 ```js
 // A 'foo' cannot be expressed in terms of any other unit.
-math.createUnit('foo') 
+math.createUnit('foo')
 math.evaluate('8 foo * 4 feet')               // 32 foo feet
 ```
