Units explained
Finger
A finger is an Imperial unit of length equal to 4.5 inches (114.3 mm). It is one of the historical English cloth-measure units.
The finger derives from English cloth-trade tradition, where it was used as a small measure for ribbons and small fabric pieces. Standardised at 4.5 inches through English customary practice.
Fingers are rare in modern use; they appear primarily in historical English textile records and bartending (where 'a finger of whisky' is an informal usage roughly 1 inch, not 4.5).
Medieval English cloth-trade origin; standardised at 4.5 inches; the value became exact via the 1959 International Yard and Pound Agreement.
Cable
A cable is a nautical unit of length equal to one tenth of a nautical mile (exactly 185.2 m). It is used in maritime navigation for short-distance descriptions.
The cable derives from the historical length of a ship's anchor cable. Standardised at one tenth of an international nautical mile in 1929.
Cables are used in modern maritime navigation when describing short distances between vessels, anchoring depths, and harbor manoeuvres. Common in naval and yachting contexts.
Standardised at 1/10 nautical mile by the International Hydrographic Organization in 1929.

Real-world example — Fabric purchase length
Two fingers of fabric equals a value in cables essential for tailors and textile buyers sourcing material from international suppliers that quote in different units.
2 finger × 0.0006171706 = 0.0012343413 cable
Real-world example — Maritime depth conversion
A 10-finger sounding depth converts cleanly into cables. Recreational divers and sailors translate between the two units whenever they read legacy charts against modern depth-sounder displays.
10 finger × 0.0006171706 = 0.0061717063 cable
Real-world example — Reference scenario in case of fallback
Conversion between human-scale length units is the everyday workflow of architecture, athletics, and apparel design — three of the most common contexts that span metric and imperial systems.
1 finger × 0.0006171706 = 0.0006171706 cable
