Mile vs Astronomical Unit: which is bigger?
A astronomical unit is the larger unit: one astronomical unit equals 92,955,810 miles. Put another way, you need 92,955,810 miles to make a single astronomical unit.
What is a Mile? History, origin and usage
The mile descends from the Roman mille passus, 'a thousand paces', where each pace was two steps of about five Roman feet, giving 5,000 Roman feet. The modern statute mile of 5,280 feet was fixed by an English statute under Queen Elizabeth I in 1593, which made the mile equal to eight furlongs.
The mile remains the standard road-distance unit in the United States and the United Kingdom and is widely understood across the English-speaking world. Speed limits in those countries are given in miles per hour.
The jump from 5,000 to 5,280 feet happened so the mile would contain a whole number of furlongs (eight), reconciling Roman and English land measures. The word 'mile' literally preserves the Latin word for 'thousand'.
What is a Astronomical Unit? History, origin and usage
The astronomical unit began as the average distance between the Earth and the Sun, a natural yardstick for the Solar System. Its older gravity-based definition subtly depended on the Sun's slowly decreasing mass, so in 2012 the International Astronomical Union redefined it as exactly 149,597,870,700 metres.
The astronomical unit is used to express distances within the Solar System, such as planetary orbits and spacecraft positions, where kilometres would be unwieldy. Earth orbits at one AU, while Neptune averages about 30 AU from the Sun.
Sunlight takes about 8 minutes and 20 seconds to cross one astronomical unit to Earth. The 2012 redefinition fixed the AU to an exact number of metres, ending its dependence on the constantly changing mass of the Sun.

Tips for converting Mile to Astronomical Unit
- To go from mile to astronomical unit, multiply by 0.0000000107578; to go back, divide by 0.0000000107578 (or multiply by 92,955,810).
- For a quick mental estimate, remember that 1 mile ≈ 0.0000000107578 astronomical unit, so 10 mile ≈ 0.000000107578 astronomical unit.
- The converter above keeps full precision; the tables round for readability, so use the tool for exact figures.
- Both fields update live as you type — change either side to convert in that direction.
How to use this Mile to Astronomical Unit converter
Type a number into the Mile field and the equivalent in Astronomical Unit appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Astronomical Unit field to convert the other way (astronomical unit to mile). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 mi = 0.0000000107578 AU), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for mile-to-astronomical unit conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Sources
- NIST Special Publication 811 — Guide for the Use of the SI — publishes the exact metric equivalents of the customary units. The inch, foot, yard and mile are defined exactly in metres by the 1959 international yard-and-pound agreement, so every imperial figure on this page is exact, not rounded.
- BIPM — The International System of Units (SI Brochure) — the defining document for the SI, published by the International Bureau of Weights and Measures. It fixes the base unit that this conversion resolves to, which is why the factor here can be exact rather than approximate.
The metric units (km, m, cm, mm, µm) are exact by definition, and the imperial units (mile, yard, foot, inch, nautical mile) use their exact international values. Traditional units (hand, span, finger, cubit, rod/pole, link, rope, ken, league) are given at their commonly accepted standard sizes — historical local values sometimes differed, so confirm against a primary source before relying on them for legal or historical work.
