Fathom (US Survey)

The fathom (US survey) is a unit of length used in U.S. surveying and nautical contexts, defined as exactly 6 US survey feet. Since one US survey foot is approximately 0.3048006096 meters, the US survey fathom measures about 1.828804 meters.

Like the international fathom, it is primarily used to measure water depths and underwater distances in marine navigation and surveying.

Key details:

1 US survey fathom ≈ 1.828804 meters

Though the difference between the US survey fathom and the international fathom is very small, the US survey units are being phased out in favor of international standards, but they still appear in some legal and historical surveying documents.

Span (Cloth)

A span is an old unit of length based on the distance between the tip of the thumb and the tip of the little finger of a fully extended hand. Traditionally, it measures about 9 inches or 22.86 centimeters.

In the context of cloth and textiles, the span was used as a convenient, informal measure to estimate small lengths of fabric before standardized rulers became widespread. It was helpful for tailors and traders to quickly gauge lengths during measuring and cutting.

While the span is largely obsolete as a formal unit today, it reflects historical measurement practices tied closely to the human body, similar to the cubit or hand.

Summary:

1 span ≈ 9 inches (22.86 cm)
Based on the hand’s spread
Used historically in cloth measurement and tailoring
Now mostly of historical and cultural interest
