# Nautical Miles to Furlongs (nmi to fur) Source: https://www.unitconvertercalculator.com/length/nautical-miles-to-furlongs/ **1 nmi = 9.2062355841883 fur** One nautical mile equals approximately 9.206 furlongs. The NM measures sea and air distances; the furlong measures horse racing. About 9.2 furlongs per NM means a nautical mile is just over a mile and a furlong. ## Formula Convert Nautical Miles to Furlongs ## Conversion Table | Nautical Miles (nmi) | Furlongs (fur) | |---|---| | 0.1 nmi | 0.92062355841883 fur | | 0.5 nmi | 4.6031177920942 fur | | 1 nmi | 9.2062355841883 fur | | 5 nmi | 46.031177920942 fur | | 10 nmi | 92.062355841883 fur | | 50 nmi | 460.31177920942 fur | | 100 nmi | 920.62355841883 fur | | 500 nmi | 4603.1177920942 fur | | 1000 nmi | 9206.2355841883 fur | | 3000 nmi | 27618.706752565 fur | | 10000 nmi | 92062.355841883 fur | ## Units ### Nautical Mile (nmi) Exactly 1852 meters by international agreement. Based on one minute of arc of latitude at the Earth's surface. The standard unit for maritime and air navigation. ### Furlong (fur) Exactly 660 feet or one-eighth of a mile (201.168 m). Originally the length of a plowed furrow. Still used in horse racing. ## Background 1 NM = 9.206 furlongs = 1.151 statute miles. A 10-furlong Kentucky Derby (1.25 miles) is about 1.086 NM. The NM-to-furlong conversion is relevant only in yacht racing near horse racing venues, which is a very specific Venn diagram. ## Good to Know Both horse racing and yacht racing measure victory in lengths of the competitor's body. A horse wins by 'lengths' (about 2.4 m). A yacht wins by 'boat lengths' (about 12 m). The NM and furlong serve different racing surfaces but share the principle of body-relative measurement. ## FAQ ### How many furlongs are in 1 nautical mile? One nautical mile contains approximately 9.206 furlongs. ### How many NM is 1 furlong? One furlong equals approximately 0.1086 NM. ### Is this conversion used? Never. Sea racing and horse racing use different units on different surfaces. ## Non-Frequently Asked Questions ### Is a nautical mile roughly 1 Derby? Almost. 1 NM = 9.2 furlongs. The Derby is 10 furlongs. So a nautical mile is about 92% of a Derby. If a yacht raced 1 NM alongside a horse racing 10 furlongs, the horse would finish about 160 m ahead. Horses beat yachts at short distances. ### Could a horse swim 1 nautical mile? Horses can swim about 0.5-2 km before exhaustion. 1 NM = 1.852 km. So a fit horse could possibly swim 1 NM, but it would be at the extreme limit. Horse-nautical-mile records are not officially tracked. The Jockey Club does not sanction marine events. ### How many boat lengths in 1 NM? A racing yacht is about 12 m (0.06 furlongs). 1 NM (1,852 m) is about 154 boat lengths. Yacht racing margins are measured in boat-lengths, just as horse racing uses lengths. Both sports measure victory in multiples of the competitor's own body. ## 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 - [Furlongs to Nautical Miles](https://www.unitconvertercalculator.com/length/furlongs-to-nautical-miles/)
