What is string tension?

The string tension or the weight force is the force that must pull on a string in order to generate the desired tone for a specified vibrating string length (VL). This force is essentially calculated and indicated using the physical unit of the Newton. However, for ease of understanding, the string tension is converted into a mass and stated in kilograms or pounds – (1 kg = 2.20462 lbs) – in the Thomastik-Infeld catalog. This mass must be attached to a string to achieve the necessary string tension and, with it, the desired tone.
