## How the conversion works

The relationship is mi = AU × 92,955,807.27. Both units measure length, so the conversion is a fixed factor that never changes. The figure is exact rather than approximate: since the international yard and pound agreement of 1959, an inch is defined as exactly 25.4 millimetres and a pound as exactly 0.45359237 kilograms, and every other imperial and US customary unit here is derived from those two.

## Common questions

### How many miles are in one astronomical unit?

One astronomical unit equals 92,955,807 miles. mi = AU × 92,955,807.27.

### How do you convert astronomical units to miles?

Use mi = AU × 92,955,807.27. So 10 AU is 929,558,070 mi.

### How many astronomical units are in one mile?

One mile equals 1.076 × 10^-8 astronomical units, which is the reverse of the conversion above.
