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 Meter
A square meter is the SI base unit of area, defined as the area of a square with sides of one meter. It is the universal scientific unit for area.
Defined by squaring the meter, which was redefined in 2019 in terms of the speed of light. The meter itself was originally proposed by the French Academy of Sciences in 1791 as 1/10,000,000 of the distance from the equator to the North Pole.
Square meters are the universal SI unit for area, used in real estate (most countries outside the US/UK), construction, physics, engineering, materials science, biology, and nearly all scientific contexts worldwide.
Meter adopted as SI base unit in 1960; current exact definition via speed of light dates to 2019.
Square Link to Square Meter conversion formula
The relationship between square links and square meters:

Step-by-step: convert square links to square meters
- Write down the value in square links (lk²).
- Multiply that value by the factor 0.040468564.
- The product is the equivalent value in square meters (m²).
- To reverse, multiply the square meter value by 24.7105382835.
Worked examples
Example 1 — Convert 1 lk² to m²:
1 × 0.040468564 = 0.040468564 m²
Example 2 — Convert 100 lk² to m²:
100 × 0.040468564 = 4.0468564 m²
Real-world example — Body height conversion
You enter your height as 180 square links into an international job or visa application. The form then asks for the same value in square meters — converting between these adjacent units is one of the most-used length conversions globally.
180 lk² × 0.040468564 = 7.28434152 m²
Real-world example — Furniture and large objects
A 72-square link piece of furniture converts to a value in square meters that's easier to mentally compare with room dimensions. This is the typical workflow when shopping internationally and product specs use a different unit than your room measurements.
72 lk² × 0.040468564 = 2.913736608 m²
Real-world example — Children's height milestones
A 150-square link-tall child measures a value in square meters that's commonly used for theme-park ride height requirements when travelling between countries that use different measurement units.
150 lk² × 0.040468564 = 6.0702846 m²
