We can base at medition of the distance that the light, c go over at certain time. Like at origin we can base at light velocity like is:

c: 299.792.458 Km/s

    The time that light delay go over at distance will be determinated by time term used together with light word. By exemple, we are speaking of years-light, months-light, days-light or seconds-lights and the others. Next chart it's indicated distances scale next to equivalent at metrical system.

CHART I

            Nomenclator:

        1mms/l: 1 milisecond light: 10^-3 sec/light.

        1ms/l: 1microsecond light: 10^-6 sec/light.

        1ns/l: 1 nanosecond light: 10^-9 sec/light.

        1ps/l: 1 picosecond light: 10^-12 sec/light.

        1fs/l: 1 femttosecond light: 10^-15 sec/light.

        1as/l: 1 attosecond light: 10^-18 sec/light.

            Equivalences:

        1 A.U.: 8.33 min./light

        1 km.: 3.34 msec./light

        1 m.: 3.34 nsec./light

    With this equivalences & with last chart; we can permit to calculate at new system of medition based with the light. Planetary distances at our Solar Sytem will be next chart:

CHART II

    The closest star to our Sun is a Centauri, at the constellation of Centaurus. It is 4.3 years-light, by the way, light from this star is late 4 years & 4 months aproximality to arrive at our Sun or our Earth. Like anecdote I can say that almost six hours is late to arrive from planet-asteroid Pluto; farest body of our Solar System at update, to Earth.

    It's interesting to used this metrical Solar System, but it has one disadvantage, decimals numbers & to used at actual society. Times to time, ...
