Is electrical conduit measured by ID or OD?
Tubing is measured by the OUTSIDE DIAMETER (O.D.), specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″).

Is nominal pipe size OD or ID?
The nominal dimension for pipe is the ID. So, 1½ inch pipe is NOT 1½ inch outside diameter, but instead is nominally, (approximately) 1½ inch inside diameter.

How do you measure the OD of a pipe?
The outside diameter is from outside edge to outside edge across the pipe. To find it, measure around the circumference of the pipe with flexible measuring tape. Divide the circumference by pi, or about 3.14159.
How do you calculate conduit size?
Since we had already calculated the total wire area, we can easily calculate the minimum conduit area: 219.98 sq. mm / 0.4 = 549.95 sq. mm. Using a simple lookup, we can find the closest conduit size. Example: If we need to use an EMT conduit, we can find that the closest conduit size is a 1 inch conduit, which gives us a 39% conduit fill.
What size wire for conduit?
Typical conduit sizes for residential application are: 3/4″, 1″ and 1-1/2″ diameter, but can be up to 6″ in diameter. Remember, the larger the wire size (for example,10 or 6 gage strands), the larger the conduit you will need.
What are the dimensions of PVC conduit?
Nominal sizes of schedule 40/schedule 80 PVC couplings range, in one-quarter inch increments, from one-half inch up to 1 1/2 inches, from 2 to 2 1/2 inches and from 3 to 8 inches. The reported size of PVC conduit couplings is the nominal, or trade size, of the corresponding pipe.
What is the diameter of electrical conduit?
The Electrical Conduit Gauge (CG1) accurately measures the “bore” or inside diameter of steel and aluminum conduit ranging in size from 0.5 inches to 4 inches (13 millimeters to 102 millimeters). This is an essential tool for every electrical installation, designed for durability and ease of use.
