# Astronomical units to yards

**1 astronomical unit in yards: 1 AU = 163,602,220,000 yd**

yd = AU × 163,602,220,800

To convert astronomical units to yards, multiply by 163,602,220,800. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is yd = AU × 163,602,220,800. 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 yards are in one astronomical unit?

One astronomical unit equals 163,602,220,000 yards. yd = AU × 163,602,220,800.

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

Use yd = AU × 163,602,220,800. So 10 AU is 1,636,022,200,000 yd.

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

One yard equals 6.112 × 10^-12 astronomical units, which is the reverse of the conversion above.
