Units explained
Square Link
A square link is an imperial unit of area equal to approximately 0.0405 m². It is part of the chain-link surveying system used historically for land measurement.
Derived by squaring the link (1/100 of a chain = 7.92 inches). The Gunter's chain was introduced by English mathematician Edmund Gunter in 1620 for land surveying.
Square links appear in historical land surveys and legacy property records, particularly in the US Public Land Survey System (PLSS). Modern surveys use feet or meters instead.
Gunter's chain introduced in 1620; standardized via the 1959 International Yard and Pound Agreement.
Square Rod
A square rod is an imperial unit of area equal to approximately 25.293 m². It is part of the historical English land survey system.
Derived by squaring the rod (16.5 feet or 1/4 chain). The rod, perch, and pole are three names for the same length.
Square rods appear in historical English and American land surveys and legacy property records. The unit is largely obsolete today, surviving mainly in legal descriptions of older land grants.
Standardized via the 1959 International Yard and Pound Agreement.

Step-by-step: convert square links to square rods
- Write down the value in square links (lk²).
- Multiply that value by the factor 0.0016.
- The product is the equivalent value in square rods (rd²).
- To reverse, multiply the square rod value by 625.0000034595.
Worked examples
Example 1 — Convert 1 lk² to rd²:
1 × 0.0016 = 0.0016 rd²
Example 2 — Convert 100 lk² to rd²:
100 × 0.0016 = 0.1599999991 rd²
Real-world example — Hardware-scale dimensions
A 10-square link fastener or component is about as long as a thumbnail. Mechanics and DIY enthusiasts convert between square links and square rods daily when mixing metric and imperial tools.
10 lk² × 0.0016 = 0.0159999999 rd²
Real-world example — Postcard and small-object dimensions
A postcard is about 5 square links wide. Converting to square rods is essential for international postal addressing forms that ask for dimensions in different units across countries.
5 lk² × 0.0016 = 0.008 rd²
Real-world example — Ruler-scale measurements
A 30-square link school ruler converts cleanly to square rods — useful when buying a desk accessory from a retailer whose product specs use a different unit.
30 lk² × 0.0016 = 0.0479999997 rd²
