Technical calculator

Gauge to Inch Calculator

Look up nominal stainless steel sheet gauge thickness in inches and millimeters.

Gauge to Inch Calculator

Enter a stainless steel sheet gauge number.

FormulaNominal thickness (in) is selected from the stainless steel gauge reference table; mm = in × 25.4.

Enter values and keep the result with the quotation assumptions.

Calculation result

Enter values and calculate.

Use the nominal gauge as a starting point, then confirm contractual thickness and tolerance with the supplier.

  • Inch and millimeter equivalents
  • Nominal thickness reminder

Technical reference

Gauge to Inch Calculator basis and limits

This calculator returns a nominal gauge reference for early sheet specification and quotation checks.

Gauge tables are nominal references. Confirm the exact thickness, standard, tolerance and supplied mill certificate.

Important Use the result for quotation preparation and early planning; it does not replace a certified measurement, drawing review or supplier confirmation.

Calculation method

Formula and worked example

01

Gauge to Inch Calculator formula

Use the inputs and units shown in the calculator, then review the assumptions before using the estimate.

Nominal thickness (in) is selected from the stainless steel gauge reference table; mm = in × 25.4.
02

Worked example

20 gauge stainless steel is approximately 0.03750 in, or 0.9525 mm, before contractual tolerance.

20 gauge → 0.03750 in × 25.4 = 0.9525 mm
