.060 There are 2 products.

A folk guitar string purchased by the unit of measure of 0.60 refers to the thickness of the string. The thickness of a guitar string is usually measured in millimeters (mm) or inches ("). However, in this case, the string is labeled with a tension measurement in kilograms-force (kgf) or pounds-force (lbf), rather than a thickness measurement.

The tension (pull) measurement of 0.60 is the force required to tension the rope to a given height, usually measured in kgf or lbf. The higher the tension measurement, the tighter the string will be and the louder and brighter the sound, but it will also be more difficult to play. Folk guitar strings come in a range of tensions, from the lightest (.010 inches) to the heaviest (.014 inches). The choice of tension depends on playing style, personal preference and the quality of the guitar.
