What is the metric trade size for 1/2 inch EMT?

• A. 12
• B. 16
• C. 20
• D. 18

Answer: (B)

Trade size is the designation used to match conduit with fittings, and when a metric equivalent is used, it’s called the metric trade size. For EMT, the imperial size of 1/2 inch corresponds to a metric trade size of 16 millimeters. That’s the standard conversion makers use so you can select compatible fittings and accessories. So the metric trade size for 1/2 inch EMT is 16. The other options don’t align with the standard metric counterpart for a 1/2 inch EMT, which is why they aren’t correct.
