Units explained
Pole
A pole is an Imperial unit of length identical to the rod and perch — 16.5 feet (about 5.03 m). The names are regional and historical variants for the same measurement.
The pole derives from medieval English land-surveying. The name comes from the physical wooden pole used by surveyors to lay out the unit on the ground.
Poles appear in historical land records, particularly older US public-land surveys. Functionally identical to rod and perch in all calculations.
Medieval English surveying origin; identical to the rod since 1620; became exact via the 1959 International Yard and Pound Agreement.
Link
A link is an Imperial unit of length equal to 7.92 inches (201.168 mm) — exactly 1/100 of a surveyor's chain. It is the smallest unit in the chain-based survey measurement system.
The link was defined by Edmund Gunter in 1620 as part of his 22-yard surveying chain. He divided the chain into 100 links specifically to enable easy decimal arithmetic when computing parcel areas.
Links appear in historical US and UK land survey documents (especially pre-1900). Modern surveyors generally use feet or meters but legacy deed records and government land surveys still cite acreage in chains and links.
Defined by Edmund Gunter in 1620; standardised as 7.92 inches via the chain definition; became exact via the 1959 International Yard and Pound Agreement.
Pole to Link conversion formula
The relationship between poles and links:
To convert poles to links, multiply the value in poles by 25. To reverse, multiply links by 0.04.

Step-by-step: convert poles to links
- Write down the value in poles (pole).
- Multiply that value by the factor 25.
- The product is the equivalent value in links (lk).
- To reverse, multiply the link value by 0.04.
Worked examples
Example 1 — Convert 1 pole to lk:
1 × 25 = 25 lk
Example 2 — Convert 100 pole to lk:
100 × 25 = 2500 lk
Real-world example — Maritime depth conversion
A 10-pole sounding depth converts cleanly into links. Recreational divers and sailors translate between the two units whenever they read legacy charts against modern depth-sounder displays.
10 pole × 25 = 250 lk
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 pole × 25 = 25 lk
Real-world example — Adult height conversion
A 1.8-pole-tall person measures a value in links 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 pole × 25 = 45 lk
