Light-second to Astronomical unit
Light-second (ls)
Astronomical unit (au)
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 ls = 299792458 m
1 au = 149597870700 m
1 ls × 299792458 = 299792458 m
299792458 m ÷ 149597870700 = 0.0020039888041 au
