Units explained
Foot
A foot is an Imperial and US customary unit of length equal to 12 inches or exactly 0.3048 meters. It is the most commonly used unit of length in everyday measurement in the United States.
The foot's origin is literally the length of a human foot, used as a measurement standard since antiquity. The English foot was standardized at various points in history; the modern international foot (0.3048 m exactly) was fixed by the 1959 International Yard and Pound Agreement.
Feet are used in the US for body height, building dimensions, room sizes, road sign clearances, aviation altitude (feet above sea level), and most everyday distance estimation. The UK uses feet informally for height despite officially being metric.
Used since antiquity; standardized to 0.3048 m exactly by the International Yard and Pound Agreement of 1959. Aviation worldwide uses feet for altitude despite metric adoption elsewhere.
Point
A point is a typographic unit equal to 1/72 of an inch (about 0.353 mm) in the PostScript point system. It is the standard unit for font sizes and typographic measurements in modern digital publishing.
The PostScript/Adobe point of exactly 1/72 inch was adopted in 1984 with the release of PostScript. This replaced earlier, slightly different typographic points (Didot, Truchet, Pica points) that had varied across regional printing traditions.
Points are used throughout typesetting, word processing, and design software for font sizes (typical body text is 10–12 pt) and small typographic dimensions. The web's standard typography unit, even when expressed in CSS as 1pt = 1.333px.
PostScript point of 1/72 inch defined by Adobe in 1984; predecessors include the Didot point (France, ~0.376 mm) and the Truchet/Pica systems.

Worked examples
Example 1 — Convert 1 ft to pt:
1 × 863.9999455748 = 863.9999455748 pt
Example 2 — Convert 100 ft to pt:
100 × 863.9999455748 = 86399.9945574807 pt
Real-world example — Macro-to-micro scale comparison
2 feet of measurement converts to a very large number in points — useful in materials science when comparing bulk-sample dimensions to feature-level surface specs.
2 ft × 863.9999455748 = 1727.9998911496 pt
Real-world example — Macroscopic to microscopic
One foot equals a million points. Optical engineers calculating coherence length compare macro-scale path lengths with micro-scale wavelength differences using exactly this conversion.
1 ft × 863.9999455748 = 863.9999455748 pt
Real-world example — Sub-meter precision
A 0.001-foot (1 mm) tolerance equals 1,000 points — useful for surface-finish specs, where macro-scale dimensions are given in the larger unit but feature roughness in the smaller.
0.001 ft × 863.9999455748 = 0.8639999456 pt
