What is a span (cloth)?

A span (cloth) is a traditional unit of length defined by the distance between the tips of the thumb and little finger on an outstretched hand, used historically in textiles.

How many millimeters are in one span (cloth)?

One span (cloth) is equivalent to 228.6 millimeters according to the standard conversion used for textile measurements.

Can I use this conversion for precise engineering?

Because the span (cloth) is non-standard and varies per individual, it is best used cautiously; for precise engineering, rely on metric units like millimeters.

Tips & Best Practices

Remember that span (cloth) is approximate and based on hand size variation.
Use millimeter results for accuracy in design and manufacturing contexts.
Cross-check conversions when precision is critical due to span variations.
Consider the historical context when converting textile measurements.
Apply this conversion primarily for rough estimation and modern documentation.

Limitations

The span (cloth) varies slightly regionally and between individuals.
Conversion to millimeters is approximate due to the non-standard nature of the span unit.
Not suitable as a sole measure in applications requiring extremely precise lengths.
Traditional units like span should be used with caution in precision engineering.
Millimeter unit conversions are reliable, but original span length may lack consistency.
