# Measurements and Math

Built into GrooCSS is the ability to do math with any compatiable Measurement types.

A Measurement is created by a number "." type notation (see below).

Measurement Math

```
def myWidth = 100.pt + 1.in // converts to pt
def myDelay = 100.ms + 1.s // converts to ms
def mySize = myWidth / 2 // you can multiply/divide with any number
def doubleSize = myWidth * 2
```
