Units explained
Pica
A pica is a typographic unit equal to exactly 12 points, or 1/6 inch (about 4.233 mm). It is used for measuring column widths and large typographic elements.
The PostScript pica of 12 points = 1/6 inch was standardised in 1984 alongside the PostScript point. Traditional pre-1984 picas varied slightly (e.g., the American pica was 0.166 inch, very close but not identical).
Picas are used for column widths in newspaper and magazine layout (typical column is 11–15 picas), line spacing in book design, and large typographic measurements. Mostly used by professional typesetters.
Modern PostScript pica defined in 1984 at 12 points = 1/6 inch; older typographic systems used slightly different pica values.
Mile
A mile (statute mile) is an Imperial and US customary unit of length equal to 5,280 feet or exactly 1,609.344 meters. It is the standard unit for road distances in the United States and the United Kingdom.
The mile derives from the Roman mille passus ("thousand paces" — about 1,480 meters). The English statute mile was fixed at 5,280 feet by the Weights and Measures Act of 1593, and exactly defined as 1,609.344 m by the 1959 International Yard and Pound Agreement.
Miles are used in the US and UK for road signs, speed limits (mph), athletic events (one-mile run), and geographic distances. Aviation also uses statute miles for some visibility measurements.
Roman origin (mille passus); English statute mile fixed at 5,280 feet in 1593; standardized to 1,609.344 m exactly by the 1959 International Yard and Pound Agreement.

Worked examples
Example 1 — Convert 1 pc to mi:
1 × 2.630471e-6 = 2.630471e-6 mi
Example 2 — Convert 100 pc to mi:
100 × 2.630471e-6 = 0.0002630471 mi
Real-world example — Small to geographic-scale
100,000 picas equals one mile — a useful conversion when small-scale survey diagrams must be related to road-network distances on a different map.
100000 pc × 2.630471e-6 = 0.263047136 mi
Real-world example — Architectural to geographic scale
A 100,000-pica measurement equals one mile. The five-order-of-magnitude scale change comes up in mapping work where architectural site plans must be related to road-network maps.
100000 pc × 2.630471e-6 = 0.263047136 mi
