Points to Miles (pt to mi)

1 point equals 2.192059484×10⁻⁷ miles (rounded).

1 point = 2.192059484×10⁻⁷ miles

How to convert points to miles

To convert points to miles, multiply the number of points by 2.192059484×10⁻⁷. The factor is rounded to 10 significant digits. To go the other way, multiply miles by 4,561,920.

miles = points × 2.192059484×10⁻⁷

Example: 10 points = 0.000002192059484 miles.

About these units

Point (pt)

Typography & screenCurrent unit

1/72 of an inch (0.3528 mm). The desktop-publishing point used by PostScript and CSS.

Printers have used a point since at least 1517, when Francesco Torniello da Novara in Milan set it at one ninth of a letter's height. Later systems differed: Fournier in 1737 used about 0.345 mm, Didot in 1783 about 0.376 mm, and the American point approved by type founders in 1886 about 0.3515 mm. TeX uses 1/72.27 inch, or 0.35146 mm, and a metric point of 0.250 mm was set by standards bodies in 1999.

The figure used here is the desktop publishing point of exactly 1/72 inch, 0.3528 mm. Xerox Interpress used it, and Adobe PostScript carried it on. W3C adopted it in 1996 for CSS, where 12 pt equals 16 px because a pixel is assumed to be 1/96 inch. NIST lists the computer point as an exact conversion. This point is about 0.4 percent longer than the TeX point. Font sizes refer to the em square rather than the printed letters.

1 point = 0.0003527777778 meters (approximately).

Mile (mi)

US & ImperialCurrent unit

5,280 feet or 1,760 yards, exactly 1,609.344 meters. This is the statute (international) mile used on US and UK roads.

A thousand paces gave the mile its name. It descends from the Latin mille passus, the Roman mile, by way of Old English mil and Middle English myle. For centuries after Rome, miles of many lengths coexisted; a sixteenth-century Mercator map, for example, shows small, medium and large Flemish miles on a single scale bar. The English statute mile was fixed by an Act of Parliament under Elizabeth I in 1593, which declared that a mile contains eight furlongs, or 5,280 feet.

The 1959 international yard and pound agreement made that mile exactly 1,609.344 meters. A slightly longer US survey mile, about 1,609.347 meters, lingered in American land surveys and was slated for retirement from 1 January 2023. Today the mile is the road unit of the United Kingdom, the United States, Liberia and Myanmar, along with several territories such as the Bahamas, Belize, Guam and the US Virgin Islands. In Canada it survives chiefly in rail transport and horse racing.

1 mile = 1,609.344 meters (exactly).
