Converting String Gauge Measurements
Gamut strings are gauged by millimeter diameter, but there are other popular gauging systems for measuring strings. The below information can be used to easily convert other gauges:
-
To change from millimeter to pirazzi-meter, divide the millimeter number by .05
-
To change from pirazzi-meter to millimeter, multiply the pirazzi-meter number by .05
-
To change from millimeter to thousandths of an inch, divide the millimeter number by 25.4
-
To change from thousandths of an inch to millimeter, multiply the thousandths number by 25.4
-
For example, a 14.5 Pirazzi-meter violin a-2 gut string × .05 = 0.725 mm.
| CONVERSION | FORMULA | EXAMPLE |
|---|---|---|
| Millimeter → Pirazzi-meter | millimeter ÷ 0.05 | 0.725 mm ÷ 0.05 = 14.5 PM |
| Pirazzi-meter → Millimeter | pirazzi-meter × 0.05 | 14.5 PM × 0.05 = 0.725 mm |
| Millimeter → Thousandths of an inch | millimeter ÷ 25.4 | 0.725 mm ÷ 25.4 = 0.0286 in (≈ 28.6 thou) |
| Thousandths of an inch → Millimeter | thousandths × 25.4 | 28.6 thou × 25.4 = 0.725 mm |
