Units explained
Centiinch
A centiinch is an Imperial unit of length equal to one hundredth of an inch (2.54×10⁻⁴ m). It is functionally identical to the caliber as a length unit but appears in different industrial contexts.
Derived from the inch via the metric-style prefix centi- (Latin centum, hundred). Standardised through the 1959 International Yard and Pound Agreement.
Centiinches occasionally appear in older engineering specifications and US-localised metric-pseudo notation. Most contemporary use prefers thousandths (mils) for sub-inch precision.
Standardised through the 1959 International Yard and Pound Agreement; rarely used in modern practice.
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.

Step-by-step: convert centiinches to poles
- Write down the value in centiinches (cin).
- Multiply that value by the factor 5.050505e-5.
- The product is the equivalent value in poles (pole).
- To reverse, multiply the pole value by 19800.
Worked examples
Example 1 — Convert 1 cin to pole:
1 × 5.050505e-5 = 5.050505e-5 pole
Example 2 — Convert 100 cin to pole:
100 × 5.050505e-5 = 0.0050505051 pole
Real-world example — Macro-scale buildup
A million centiinches equals exactly one pole — the conversion that bridges microscale features and macroscale objects in microfluidic, biomedical, and semiconductor packaging design.
1000000 cin × 5.050505e-5 = 50.5050505051 pole
Real-world example — Quarter-meter measurement reference
A 250,000-centiinch length equals 0.25 poles — useful for comparing supply-chain spec sheets where some lengths are quoted in the smaller unit and some in the larger.
250000 cin × 5.050505e-5 = 12.6262626263 pole
Real-world example — From microscopic to macroscopic
A million centiinches equals exactly one pole. This kind of conversion appears in microfluidics, where total channel length is given in poles but feature widths are in centiinches.
1000000 cin × 5.050505e-5 = 50.5050505051 pole
