Didot point to Light-year
Didot point (dd)
Light-year (ly)
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 dd = 0.000376065 m
1 ly = 9.46073047e15 m
1 dd × 0.000376065 = 0.000376065 m
0.000376065 m ÷ 9.46073047e15 = 3.97501019e-20 ly
