# unitRaised(toPower:)

Creates a complex unit by raising the unit to the given power.

```
func unitRaised(toPower power: Int) -> HKUnit
```

## Parameters

`power`

The power by which to raise the unit.

## Return Value

A new, complex unit.

## Discussion

This method creates a new, complex unit by raising the unit this method is called on by the given power. This task is often only one step in a series of operations. For example, you can use this method to create a meters-per-second-squared unit as shown below.

```swift
let meters = HKUnit.meterUnit()
let seconds = HKUnit.secondUnit()
let squaredSeconds = seconds.unitRaisedToPower(2)
let metersPerSecondSquared = meters.unitDividedByUnit(squaredSeconds)
```
