Units explained
Hand
A hand is an Imperial unit of length equal to 4 inches (101.6 mm). It is used primarily to measure the height of horses at the withers.
The hand derives from the average breadth of a human hand and was standardised at exactly 4 inches by the Statute of Henry VIII in 1541.
Hands are used worldwide for horse height specification (the typical riding horse is 14–17 hh). Also used in some equestrian-adjacent contexts. The unit is now almost exclusively a horse-measurement convention.
Standardised at 4 inches by Henry VIII in 1541; value became exact in 1959 when the inch was fixed at 25.4 mm.
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.

Real-world example — Fabric purchase length
Two hands of fabric equals a value in fingers essential for tailors and textile buyers sourcing material from international suppliers that quote in different units.
2 hh × 0.8888888889 = 1.7777777778 finger
Real-world example — Maritime depth conversion
A 10-hand sounding depth converts cleanly into fingers. Recreational divers and sailors translate between the two units whenever they read legacy charts against modern depth-sounder displays.
10 hh × 0.8888888889 = 8.8888888889 finger
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 hh × 0.8888888889 = 0.8888888889 finger
