Multiply the number of Nautical Miles by 92.0624 to get Chains. Formula: chain = nmi × 92.0624. Example: 10 nmi × 92.0624 = 920.624 chain. To reverse, divide Chains by 92.0624 to get Nautical Miles.

| 0.01 nmi | 0.920624 chain |
| 0.1 nmi | 9.20624 chain |

To convert Nautical Mile to Chain, multiply by 92.0624. Example: 10 nmi = 920.624 chain
To convert Chain back to Nautical Mile, divide by 92.0624 (multiply by 0.0108622). Use the swap button above.
Start with 100 Nautical Miles = 9206.24 chain as your reference point. Scale up or down from there.
Coastal boundary surveys record land dimensions in chains and maritime distances in nautical miles. Surveyors producing integrated coastal management maps convert between the two for consistent georeferencing of land and sea boundaries.
Victorian harbour construction drawings used chains for land-side quay lengths and nautical miles for channel approach distances. Engineers restoring these harbours convert between the two using original survey records.
Port development planning applications reference land dimensions in chains (from title deeds) and sea distances in nautical miles (from maritime consenting). Project engineers convert between both in the same planning document.
Historic UK fisheries regulations defined inshore zones in chains from the shoreline and offshore zones in nautical miles. Legal researchers interpreting these historic regulations convert between chain and nautical mile measurements.
Long-distance coastal paths like the South West Coast Path were originally surveyed in chains for land sections while nautical miles described headland-to-headland distances. Route planners convert between both when producing accurate guides.
Comprehensive converters include nmi-to-chain for coastal engineers, maritime historians, and legal researchers working with documents where both land survey (chains) and maritime (nautical miles) measurement systems appear together.
The Nautical Mile is a unit of Length measurement (symbol: nmi). 1 nmi = 92.0624 chain. Used in scientific and practical Length measurement applications.
The Chain is a unit of Length measurement (symbol: chain). It is part of an internationally recognised measurement system used alongside the Nautical Mile.
The nautical mile was defined by Earth's own geometry — one minute of arc of latitude along a meridian, approximately 1,852 metres. This elegant definition made it perfect for navigation: on any nautical chart, one nautical mile equals exactly one arcminute, allowing direct distance measurement with dividers without any conversion. The unit was used informally by mariners for centuries before the International Hydrographic Conference standardised it at exactly 1,852 metres in 1929. Today it is universally used in maritime and international aviation — the only two domains that never adopted kilometres for operational distances, largely because the geometric relationship to Earth's circumference remains too useful to abandon.
Edmund Gunter invented the surveyor's chain in 1620. His design — 100 links totalling exactly 66 feet — was brilliantly chosen: 10 chains × 10 chains = 1 acre. 80 chains = 1 mile, 10 chains = 1 furlong. The chain became the standard survey unit across the British Empire and is written into American law — the US Public Land Survey System still divides land using chains and links.
Common use: Nautical Mile to Chain conversion is needed when working with international standards, scientific publications, or reference materials that use different unit systems for Length measurement.
