Gauge To Inches Calculator

Input either the gauge number or the thickness, and this calculator will compute the missing value.

The Gauge to Inches Calculator simplifies conversions between metal gauge numbers and thickness measurements. Metal gauges are widely used in industries like construction, manufacturing, and automotive to specify material thickness. This tool assists in converting gauge numbers to precise thickness values in various units, such as inches, millimeters, or centimeters, for accurate measurements and material selection.

Formula

• Thickness (in):

  $$\text{Thickness (in)} = \frac{\text{Gauge Number}}{39.37}$$

• Gauge Number:

  $$\text{Gauge Number} = \text{Thickness (in)} \times 39.37$$

Solved Calculations

Example 1:
Convert Gauge Number to Thickness:

• Gauge Number = 20

Example 2:
Convert Thickness to Gauge Number:

• Thickness = 0.2 in
