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.
Perch
A perch is an Imperial unit of length identical to the rod — 16.5 feet (about 5.03 m). The names 'rod', 'perch', and 'pole' all refer to the same surveying unit and differ only by regional preference.
Like the rod, the perch derives from medieval English land-surveying. The name 'perch' was particularly common in legal land descriptions in Ireland and parts of the UK.
Perches appear in legacy land descriptions in Ireland, the UK, and historical US documents. Modern usage is rare.
Medieval English surveying origin; identical to the rod since 1620; became exact via the 1959 International Yard and Pound Agreement.

Worked examples
Example 1 — Convert 1 hh to perch:
1 × 0.0202020202 = 0.0202020202 perch
Example 2 — Convert 100 hh to perch:
100 × 0.0202020202 = 2.0202020202 perch
Real-world example — Adult height conversion
A 1.8-hand-tall person measures a value in perches that converts the height to the unit favoured by American forms, schools, or driver's licences. This is daily routine for anyone living between metric and imperial systems.
1.8 hh × 0.0202020202 = 0.0363636364 perch
Real-world example — Fabric purchase length
Two hands of fabric equals a value in perches essential for tailors and textile buyers sourcing material from international suppliers that quote in different units.
2 hh × 0.0202020202 = 0.0404040404 perch
Real-world example — Maritime depth conversion
A 10-hand sounding depth converts cleanly into perches. Recreational divers and sailors translate between the two units whenever they read legacy charts against modern depth-sounder displays.
10 hh × 0.0202020202 = 0.202020202 perch
