Which device uses JTS LineString.getLength ()

I am trying to figure out which device returns JTS LineString.getLength ().

eg:

LineString foo = (initialize line string somehow)
foo.getLength() -> 7.025667228118838E-4

Are these kilometers ?, meters ?, feet?

Depending on in which part your coordinate geometries are expressed. If your coordinates are in meters, the perimeter will also be in meters.

com.vividsolutions.jts.geom.Geometry.getLength () returns the length / perimeter in meters. com.vividsolutions.jts.geom.Geometry.getArea () returns the area in square meters.
