Units explained
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.
Centimeter
A centimeter is a metric unit of length equal to one hundredth of a meter (1/100 m). It is one of the most commonly used SI sub-units in daily life, especially for measuring small objects, body dimensions, paper sizes, and short distances.
The centimeter emerged from the French metric system established by the French Academy of Sciences in 1793. The metric system introduced decimal-based prefixes (milli-, centi-, deci-, deca-, hecto-, kilo-) to create proportional sub-units of the meter.
Centimeters are the standard unit for everyday measurement in nearly every country outside the United States. They are used for body height, clothing sizes, rainfall, paper formats (A4 is 21 × 29.7 cm), screen dimensions, and most consumer product specifications.
Developed in France during the late 18th century as part of the metric system designed by the French Academy of Sciences. Formally adopted in France in 1795 and ratified internationally through the Metre Convention signed in Paris in 1875.

Step-by-step: convert links to centimeters
- Write down the value in links (lk).
- Multiply that value by the factor 20.1168.
- The product is the equivalent value in centimeters (cm).
- To reverse, multiply the centimeter value by 0.0497096954.
Worked examples
Example 1 — Convert 1 lk to cm:
1 × 20.1168 = 20.1168 cm
Example 2 — Convert 100 lk to cm:
100 × 20.1168 = 2011.68 cm
Real-world example — Body height conversion (reverse direction)
You measure 1.75 links tall and need to fill in a gym membership form or medical record that asks for height in centimeters. This is the most-used everyday length conversion in metric-using countries.
1.75 lk × 20.1168 = 35.2044 cm
Real-world example — Pet and accessory dimensions
A 3-link dog leash equals a tidy round value in centimeters. Pet-supply shopping frequently mixes the two units across product specifications.
3 lk × 20.1168 = 60.3504 cm
Real-world example — Fabric and tailoring
One link of fabric converts to a value in centimeters commonly used for seam allowances. Garment patterns frequently switch between the two units on a single instruction sheet.
1 lk × 20.1168 = 20.1168 cm
