Units explained
Mil
A mil (also called a thou) is an Imperial unit of length equal to one thousandth of an inch (1/1000 in = 0.0254 mm = 25.4 μm exactly). It is used in engineering, manufacturing, and materials specifications.
The mil is derived from the Latin mille, "thousand," denoting one-thousandth of an inch. Standardized in industrial use during the 19th-century rise of precision engineering.
Mils are used to specify thicknesses of plastic films, foils, paper, copper traces on printed circuit boards (PCBs), wire insulation, and paint coatings. A standard sheet of paper is about 4 mils thick.
Adopted in 19th-century engineering practice; the value (1/1000 in) became exact in 1959 when the inch was fixed at 25.4 mm via the International Yard and Pound Agreement. The British term is "thou"; American term is "mil".
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.

Step-by-step: convert mils to links
- Write down the value in mils (mil).
- Multiply that value by the factor 0.0001262626.
- The product is the equivalent value in links (lk).
- To reverse, multiply the link value by 7920.
Worked examples
Example 1 — Convert 1 mil to lk:
1 × 0.0001262626 = 0.0001262626 lk
Example 2 — Convert 100 mil to lk:
100 × 0.0001262626 = 0.0126262626 lk
Real-world example — Quarter-meter measurement reference
A 250,000-mil length equals 0.25 links — useful for comparing supply-chain spec sheets where some lengths are quoted in the smaller unit and some in the larger.
250000 mil × 0.0001262626 = 31.5656565657 lk
Real-world example — From microscopic to macroscopic
A million mils equals exactly one link. This kind of conversion appears in microfluidics, where total channel length is given in links but feature widths are in mils.
1000000 mil × 0.0001262626 = 126.2626262626 lk
Real-world example — Macro-scale buildup
A million mils equals exactly one link — the conversion that bridges microscale features and macroscale objects in microfluidic, biomedical, and semiconductor packaging design.
1000000 mil × 0.0001262626 = 126.2626262626 lk
