Ri to Astronomical unit

How it is calculated

Each unit is defined via the base unit (meter (m)). The value is first converted to the base unit, then to the selected unit.

1 ri = 3927.27272727 m

1 au = 149597870700 m

1 ri × 3927.27272727 = 3927.27272727 m

3927.27272727 m ÷ 149597870700 = 2.62521967e-8 au
