Units explained
Nail
A nail is an Imperial unit of length equal to 2.25 inches (about 57.15 mm). It was historically used in the English cloth trade.
The nail derives from an English cloth-measure tradition dating to medieval times. Standardised at 2.25 inches (or 1/16 of a yard) through English customary practice and ratified by the 1959 International Yard and Pound Agreement.
Nails were historically used to measure cloth, particularly small pieces and ribbons. Rare in modern commerce but appears in historical textile literature and reproduction crafts.
Medieval English cloth-trade origin; standardised at 1/16 yard; fixed exactly at 0.05715 m via the 1959 International Yard and Pound Agreement.
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.

Worked examples
Example 1 — Convert 1 nail to mi:
1 × 3.551136e-5 = 3.551136e-5 mi
Example 2 — Convert 100 nail to mi:
100 × 3.551136e-5 = 0.0035511364 mi
Real-world example — Architectural to geographic scale
A 100,000-nail 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 nail × 3.551136e-5 = 3.5511363636 mi
Real-world example — Small to geographic-scale
100,000 nails equals one mile — a useful conversion when small-scale survey diagrams must be related to road-network distances on a different map.
100000 nail × 3.551136e-5 = 3.5511363636 mi
