About these units
Fathom (fath)
A fathom is equal to 6 feet and is historically associated with maritime measurement. Its origins may lie in the approximate span of a fully outstretched human arms, which was convenient for measuring rope lengths by hand aboard ships. Sailors used the fathom to estimate water depth through weighted lines, giving rise to the practice of "sounding" the depths. The fathom became a cornerstone unit in nautical life because it fits the human scale while also being large enough to measure significant underwater distances. Charts, sonar readings, and older depth gauges frequently utilized fathoms, although modern equipment increasingly displays depths in meters. Still, many mariners—particularly in regions using imperial measurements—continue to think instinctively in fathoms when estimating safe anchoring or navigating shallow waters. The unit persists as an important piece of maritime history and remains in active use by traditional sailors, divers, and some fishing industries. Its survival reflects the enduring cultural heritage of nautical practice.
Ell (ell)
The ell is a traditional European unit of length, varying between 45–70 cm depending on the region. It originated from the forearm or arm length and became standardized in many countries for measuring cloth and textiles. In commerce, the ell simplified transactions, allowing merchants to describe fabric lengths efficiently. In tailoring, it offered a consistent basis for cutting and patterning clothing. The unit was essential in guild systems, where precision and repeatability in textile production were critical. While largely obsolete today due to the metric system, the ell remains significant for historians, textile scholars, and anyone studying pre-modern European commerce and craft practices.
