> How much to scale the tree model compared to what is in the imported SpeedTree model file.

## Definition

* **Type:** Property
* **Namespace:** [UnityEditor](/engine/6000.0/script-reference/unityeditor.md)
* **Assembly:** UnityEditor

```csharp
public float scaleFactor { get; set; }
```

### Remarks

In the Unity Editor, the SpeedTreeImporter provides a dropdown with the following unit conversion options, which drive the `scaleFactor` value:

0 - LeaveAsIs : 1.0

1 - FeetToMeters : 0.3048

2 - CentimetersToMeters : 0.01

3 - InchesToMeters : 0.0254

4 - CustomConversion : user specified value

By default, the SpeedTree Modeler exports units in feet. Because Unity's default units are meters, the default value for `scaleFactor` is set to `0.3048`.
