What is the diameter of a #6 re-bar?

1/2 inch
5/8 inch
3/4 inch
1 inch

The correct answer is: 3/4 inch

The diameter of a #6 re-bar is actually 3/4 inch. Re-bar sizes in the United States are defined by the number of eighths of an inch of the bar's diameter. For a #6 re-bar, this means it has a diameter of 6/8 inch, which simplifies to 3/4 inch. Understanding the sizing system for re-bar is crucial for construction projects, as the diameter directly affects the load-bearing capacity and structural integrity of concrete reinforcements. Knowing this sizing helps ensure that the correct materials are used for specific applications, adhering to safety and engineering standards in construction.
