Unit is a utility for handling and converting bitcoin units. We strongly recommend to always use satoshis to represent amount inside your application and only convert them to other units in the front-end. Unit is a utility for handling and converting bitcoin units. We strongly recommend to always use satoshis to represent amount inside your application and only convert them to other units in the front-end.
To understand the need of using the `Unit` class when dealing with unit conversions, see this example:
```
> 81.99 * 100000 // wrong
8198999.999999999
> var bitcore = require('bitcore');
> var Unit = bitcore.Unit;
> Unit.fromMilis(81.99).toSatoshis() // correct
8199000
```
