It might be light also because distance is a scalar quantity.

Light year means a light is the distance travelled in one year is 1 light year and it is used to measure distance so, one light is equal to 9.4 *10^15.

Distance travelled by a light in one year in vacuum.
Distance travelled = velocity of light * one year
1 light year = 9.467 *10^15 m.
