Google Maps V3 API -- geometry library is using what distance measure?

I'm using the google.maps.geometry.spherical's "computeDistanceBetween" function to get the distance between two points on a map. I get a numeric value just fine, but does anyone know what units it's in? (Meters? Yards?) And is it possible to pass a parameter into the function to return, say miles? If there's a conversion utility function I'd be grateful to know of it.

I've looked at Google's API documentation but can't see anything about th开发者_JAVA百科e units of measure being returned. (I'm probably looking in the wrong place.) Thanks for the help.

You set the unit you want to use.
