What’s the difference between string gauge and tension?
What’s the difference between string gauge and tension? What does they mean? :)
Gauge means diameter, and tension means pull. Tension is proportional to the square of the gauge.
With a string of the same brand and type, a thicker gauge will usually give a higher tension, and thinner will give a lower tension.
Gauge is an alternate way to specify the diameter of a string. You have to be careful when using it because a SMALLER gauge means a BIGGER diameter, which is counter-intuitive to actually specifying the diameter of the string in, say, millimeters.
To amplify the "all things equal": wound strings aren't all things equal. The winding confounds the equation, as David mentioned, depending on whether it's lead or plastic foam, to state an extreme. So the equation only applies to pure wire of identical composition(!). The tension of a wound string depends a lot on the core material and size figured against the weight (not diameter) of the wrapping, against the intended pitch, to oversimplify.
Another common "gauge" used for strings is a set of terms which is descriptive of the thickness so, therefore, the tension needed to bring the string up to pitch. Examples are:
