# Token Units

**1 meey *****= 1*****  10^9 mgas = 1  *****10^18 gas***

Note that amounts in the base unit gas exceed the range of 64-bit integers. You need some implementation of Big Integer to deal with these numbers. Meey SDKs come bundled with a recommended way to do that. In most cases, you can just use strings instead of numbers. For example, when creating a JSON transaction, set

```
{
    "amount": "1000000000000000000"
}
```
