Terne is gauged by which gauge system?

• A. Metric Gauge
• B. U.S. Standard Gauge
• C. Decimal Inches System
• D. British Imperial Gauge

Answer: (B)

In sheet metal practice, terne plate thickness is specified using the U.S. Standard Gauge. This system assigns gauge numbers to thicknesses, with higher gauge numbers meaning thinner material, and it’s the standard reference used for terne and other sheet metals in the U.S. The other options aren’t the standard for gauging terne—metric gauge would use millimeters, decimal inches would give a direct thickness in inches rather than a gauge number, and British Imperial gauge isn’t the common reference for terne in this context.
