Which term is a measurement of thickness of metals and includes examples such as 18 gauge and 20 gauge?

• A. Foot Candle
• B. Gimp
• C. Gauge
• D. Grave Box

Answer: (C)

Gauge is the term used to describe the thickness of metal. The numbers like 18 gauge and 20 gauge refer to thickness on gauge charts, with lower numbers meaning thicker metal. Different metals have their own gauge tables, so the exact thickness for 18 gauge steel isn’t the same as 18 gauge aluminum, but the concept remains: gauge measures sheet metal thickness. The other terms don’t denote thickness—foot candle is a unit of light level, gimp isn’t a metal-thickness term, and grave box isn’t a measurement term.
