Units explained
Kilometer
A kilometer is a metric unit of length equal to one thousand meters. It is the standard unit for measuring road distances, geographic distances, and other large-scale measurements in metric countries.
The kilometer was defined alongside the meter in 1795 using the standard SI prefix kilo- (from Greek chilioi, "thousand"), denoting one thousand units.
Kilometers are used worldwide (except the United States and a few others) for road signage, geographic distance, athletic events, and scientific distances at planetary scale. Speed limits in most countries are given in km/h.
Adopted 1795 in France as part of the original metric system; the kilometer became the global standard for road and geographic distance through the 19th and 20th century metric adoption.
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 km to pt:
1 × 2834645.490730993 = 2834645.490730993 pt
Example 2 — Convert 100 km to pt:
100 × 2834645.490730993 = 2.834645e+8 pt
Real-world example — Long-haul to feature-scale
One kilometer equals one billion points — useful in fiber-optic engineering, where total cable length is given in the larger unit but feature-level attenuation depends on micro-scale variations.
1 km × 2834645.490730993 = 2834645.490730993 pt
Real-world example — Geographic to fiber-optic scale
One kilometer equals one billion points. This conversion appears in fiber-optic specifications, where total link length is given in kilometers but signal attenuation depends on micro-scale variations along the fiber.
1 km × 2834645.490730993 = 2834645.490730993 pt
