# Fathoms to Hands (ftm to hh) Source: https://www.unitconvertercalculator.com/length/fathoms-to-hands/ **1 ftm = 18 hh** One fathom equals exactly 18 hands. Since 1 fathom = 6 feet = 72 inches, and 1 hand = 4 inches, divide 72 by 4 to get 18. Both units are based on the human body: the fathom from outstretched arms, the hand from palm width. Their ratio is a clean 18:1. ## Formula Convert Fathoms to Hands ## Conversion Table | Fathoms (ftm) | Hands (hh) | |---|---| | 0.25 ftm | 4.5 hh | | 0.5 ftm | 9 hh | | 1 ftm | 18 hh | | 2 ftm | 36 hh | | 5 ftm | 90 hh | | 10 ftm | 180 hh | | 20 ftm | 360 hh | | 50 ftm | 900 hh | | 100 ftm | 1800 hh | | 200 ftm | 3600 hh | | 500 ftm | 9000 hh | | 1000 ftm | 18000 hh | | 6000 ftm | 108000 hh | ## Units ### Fathom (ftm) Exactly 6 feet (1.8288 m). Traditionally used to measure water depth in nautical contexts. Originally based on the span of outstretched arms. ### Hand (hh) Exactly 4 inches (10.16 cm). The standard unit for measuring the height of horses, measured from the ground to the withers. ## Background A fathom is 18 hands tall. A horse standing 16 hands at the withers is about 0.889 fathoms. Shakespeare's 'full fathom five' (5 fathoms = 90 hands) is about 5.6 horse-heights of water. Both units derive from body parts, making them among the most ancient forms of measurement. ## Good to Know Both the fathom and the hand are measurements taken directly from the human body. Sailors measured rope by stretching their arms (1 fathom). Horse traders measured withers by stacking palms (hands). Both practices go back thousands of years. ## FAQ ### How many hands are in 1 fathom? One fathom contains exactly 18 hands. Since 1 fathom = 72 inches and 1 hand = 4 inches, divide 72 by 4. ### How do I convert fathoms to hands? Multiply the fathom value by 18. For example, 3 fathoms = 54 hands. The conversion is exact. ### Are fathoms and hands both body-based units? Yes. The fathom comes from the span of outstretched arms (about 6 feet). The hand comes from palm width (about 4 inches). Both are among the oldest body-derived measurement units still in use. ## Non-Frequently Asked Questions ### How many horses stacked equals one fathom? A fathom is 18 hands (6 feet / 4 inches per hand). A 16-hand horse is about 0.889 fathoms tall. So stacking 1.125 horses (one horse plus a short pony on top) gives you one fathom. This is not a recommended equestrian configuration. ### Is the ocean measured in horses? Not officially. But since 1 fathom = 18 hands, the Mariana Trench at 6,011 fathoms is about 108,198 hands deep. That is 6,762 horses stacked. The ocean is 6,762 horses deep. You are welcome for this information. ### Were fathoms and hands ever used by the same person? Possibly. A sailor who also owned horses would measure water depth in fathoms and horse height in hands. Both are body-based units from the English tradition. The same arm span that defined a fathom belonged to a man who might have measured his horse in hands. ## Related Articles - [Why We Measure: The Deepest Urge in Human Civilisation](https://www.unitconvertercalculator.com/blog/why-we-measure) - [The Map Is Not the Territory: Why Every Measurement Is Wrong](https://www.unitconvertercalculator.com/blog/the-map-is-not-the-territory) - [Zero: The Most Dangerous Number in Measurement](https://www.unitconvertercalculator.com/blog/zero-the-most-dangerous-number-in-measurement) - [The Body as a Ruler: Every Measurement Unit That Came From Us](https://www.unitconvertercalculator.com/blog/the-body-as-a-ruler) - [The Speed of Everything: How We Measure From Glaciers to Light](https://www.unitconvertercalculator.com/blog/the-speed-of-everything) - [15 Obscure Measurement Units You've Never Heard Of (But Still Need)](https://www.unitconvertercalculator.com/blog/obscure-measurement-units-guide) - [When Measurements Go Wrong - Disasters, Blunders and Happy Accidents](https://www.unitconvertercalculator.com/blog/when-measurements-go-wrong) - [The Surprising Stories Behind Everyday Units of Measurement](https://www.unitconvertercalculator.com/blog/stories-behind-measurement-units) - [Metric vs. Imperial - The Complete Guide to the World's Two Measurement Systems](https://www.unitconvertercalculator.com/blog/metric-vs-imperial-complete-guide) - [Length & Distance Conversion Guide - Meters, Feet, Miles & Kilometers](https://www.unitconvertercalculator.com/blog/length-and-distance-guide) ## See Also - [Hands to Fathoms](https://www.unitconvertercalculator.com/length/hands-to-fathoms/)
