**You can multiply the bar size by 1/8 to get the nominal diameter in inches. For example, #8 rebar = 8/8 inches (or 1 inch) in diameter. Common measurements indicate the weight, nominal area, and nominal diameter.**

## How to Measure Rebar Diameter?

Measuring the diameter of rebar can be a tricky task. Rebar, or reinforcing bar, is used in construction to reinforce concrete structures and provide additional strength.

Rebar is typically made from steel, and can be found in a variety of sizes, from 1/4 inch to 1 inch in diameter. Knowing the diameter of the rebar you are working with can be critical to the success of the project.

Fortunately, there are a few simple ways to measure the diameter of rebar accurately. The most accurate way to measure the diameter of rebar is to use a caliper. A caliper is a precision measuring tool that can measure the exact diameter of an object.

To use a caliper, open the jaws of the caliper wide enough to fit the rebar between the jaws of the caliper. Make sure the jaws are lined up with the center of the rebar.

Then, close the jaws of the caliper slowly, until they just touch the sides of the rebar. The measurement displayed on the caliper will be the diameter of the rebar.

Another way to measure the diameter of rebar is to use a tape measure. To do this, wrap the tape measure around the rebar, making sure the tape measure
