# convert(_:toFamily:)

Returns a font whose traits are as similar as possible to those of the given font except for the font family, which is changed to the given family.

```
func convert(_ fontObj: NSFont, toFamily family: String) -> NSFont
```

## Parameters

`fontObj`

The font whose traits are matched.

`family`

The new font family; a generic font name, such as Helvetica or Times.

## Return Value

A font with matching traits and the given family, or `aFont` if it can’t be converted.

## Discussion

This method attempts to match the weight and posture of `aFont` as closely as possible. Italic is mapped to Oblique, for example. Weights are mapped based on an approximate numeric scale of 0 to 15.

## See Also

[`convert(_:)`](/documentation/AppKit/NSFontManager/convert(_:))

Converts the given font according to the object that initiated a font change, typically the Font panel or Font menu.
