## How the conversion works

The relationship is m = AU × 149,597,870,700. Both units measure length, so the conversion is a fixed factor that never changes.

## Common questions

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

One astronomical unit equals 149,597,870,000 meters. m = AU × 149,597,870,700.

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

Use m = AU × 149,597,870,700. So 10 AU is 1,495,978,700,000 m.

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

One meter equals 6.685 × 10^-12 astronomical units, which is the reverse of the conversion above.
