🧮 Formula

Meters to Astronomical Units
AU = m × 6.68459 × 10⁻¹²
Astronomical Units to Meters
m = AU × 149,597,870,700

Where

  • m = the length in meters
  • AU = the length in astronomical units
Every unit here is defined by its length in meters, so the conversion factor is (meters per meter) ÷ (meters per astronomical unit).
