How this calculation works: NPS / DN / OD Cross Reference — Companion Article

NPS / DN / OD

Look up a pipe nominal size or outside diameter. NPS, DN and outside diameter are read from stored pipe records. This page does not store a size chart. Metric shows outside diameters in millimetres, with inches in brackets. Imperial does the reverse.

Catalogue values are evidence from the source catalogue. They are not a code-approved size-conversion table.
