Is conduit measured by ID or OD?
The ID and OD
This is a fixed number that can not be deviated from. For instance, a 1-inch rigid conduit will have an ID of 1.063 inch nominal while a 1 inch intermediate metallic conduit will have an ID of 1.12 inch nominal, yet both have the same knockout size of 1.375 inches.

Is nominal pipe size OD or ID?
The nominal dimension for pipe is the ID . So, 11⁄2 inch pipe is NOT 11⁄2 inch outside diameter, but instead is nominally, (approximately) 11⁄2 inch inside diameter. Pipe is typically manufactured to looser tolerances and less expensive to purchase.
What are the 4 common sizes of conduit?
Some typical US Customary trade sizes for conduit are 1⁄2, 3⁄4, 1, and up to 4 . Outside the US, conduit sizes are typically measured in millimeters and are based on the outer diameter. Some common metric outer diameter sizes are 20 mm, 25 mm, 32 mm, 40 mm and 50 mm.
Is PVC measured by ID or OD?
PVC Pipe is identified by the ID (Inside Diameter) and is referred to as a “nominal” size which means “in name only.” However this confuses people and most novices try to use the OD (Outer Diameter) to order parts. If you do this, measure the OD of your pipe and find it the 2 nd column of the chart below.

What size conduit do I need for 12 2 wire?
For two 12/2 NM cable, you need at least 1′′ conduit (by calculations below) but it’ll still be a difficult pull. For two 12/2 UF, you’ll need at least 1-1/4′′ conduit.
How do I measure conduit size?
Calculate the total diameter of the wires to determine the diameter of the conduit when placing wires of different gauge and type inside the conduit. Find the wire diameter in table 5 for each gauge wire and type. Multiply the number of wires for each gauge and type by the wire diameter. Total the results.
How do you measure the diameter of a conduit?
- Wrap a string around the pipe.
- Mark the point where the string touches together.
- Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference)
- Divide the circumference by 3.14159.
