What is a span (cloth) used for?

A span (cloth) was traditionally used to measure narrow fabric widths and small textile pieces based on the distance between an outstretched thumb and little finger.

Why use the UK nautical mile instead of the international one?

The UK nautical mile was historically defined by the Admiralty and is slightly longer than the international nautical mile, important for interpreting British maritime records.

Are conversions exact between these units?

No, because the span (cloth) is an informal unit with some variability and the UK nautical mile differs from the international standard, conversions are approximate.

Examples

10 Span (cloth) converts to approximately 0.001233553 NM (UK).
100 Span (cloth) converts to approximately 0.01233553 NM (UK).

Common Use Cases

Interpreting narrow fabric widths in historical textile documents.
Translating legacy maritime distances recorded in UK nautical miles for navigation history.
Converting old trade or maritime records for use in modern standardized units.
Museum and archival work involving measurement unit reconciliation.

Tips & Best Practices

Remember the span (cloth) is an informal measurement and may vary slightly due to hand size differences.
Note that the UK nautical mile is distinct from the international nautical mile, especially for precise navigation needs.
Verify the context of your historical data to select the correct nautical mile definition.
Use the tool primarily for approximate conversions rather than exact scientific calculations.

Limitations

Span (cloth) is a traditional, informal unit that involves natural human variation in length.
The UK nautical mile differs slightly compared to the international nautical mile used today.
Conversions are approximate and best suited for historical or archival purposes, not modern precision navigation.
