What is the BWG gauge tube wall thickness that is closest to 1/8 inch?

The correct answer is: 11

The BWG, or Birmingham Wire Gauge, defines the thickness of metal sheets and tubes, with lower numbers indicating thicker walls. To find the gauge that corresponds closely to 1/8 inch, it’s important to convert that measurement into a decimal format. One-eighth of an inch is equal to 0.125 inches. When evaluating the BWG gauge values, gauge number 11 has a wall thickness of approximately 0.120 inches, while gauge number 12 comes in at about 0.105 inches. Since 0.120 inches (gauge 11) is the closest measurement to 0.125 inches, this is why gauge number 11 is identified as the appropriate choice. In contrast, gauge numbers 10 and 13 have wall thicknesses of roughly 0.135 inches and 0.090 inches, respectively, making them less fitting options for a value closest to 1/8 inch. Understanding BWG and its measurement helps in accurately selecting the appropriate tube wall thickness for piping systems.
