Pipe size conversions are useful for plumbing, irrigation, drainage, water lines, pipe fittings, conduit planning, pipe replacement, flow estimates, and material comparisons.
Use this converter when comparing nominal size to actual outside diameter, inside diameter, wall thickness, and metric measurements.
Your result shows the selected nominal pipe size converted into actual reference dimensions. It includes outside diameter, approximate inside diameter, wall thickness, and metric equivalents.
Pipe dimensions can vary by manufacturer, material standard, pressure rating, and schedule. Always verify dimensions with the pipe or fitting manufacturer for code or pressure-critical work.
No. Nominal pipe size is a trade size. The actual outside diameter is often different from the nominal size.
Common 1/2 inch PVC Schedule 40 pipe has an outside diameter of about 0.840 inches.
Common 3/4 inch PVC Schedule 40 pipe has an outside diameter of about 1.050 inches.
Pipe sizes are based on historical nominal sizing systems. Actual dimensions depend on pipe standard, wall thickness, and material type.
No. A pipe size converter compares nominal pipe sizes with common actual dimensions. A pipe diameter converter usually converts measured diameters between units.
