Below is a checklist of Metric measurements (consisting of numbers and their associated metric units) on postal items (stamps, souvenir sheets, aerogrammes, postal cards, etc.). Catalog numbers, years of issue, and notes on the items featured are given when available. If readers know of additional information or images, please contact the author using the e-mail address at the bottom of this page.
This list does not include postal items specifically about the metric system (SI), many of which show specific metric units.
This list does not include cachets on (non-FDC) covers, as there are way too many of these types of items with metric measurement units on them.
