    SI units are fun!

    My car needs 7 liters of gas per 100 km.
    7 liters / 100 km =
    7 dm³ / 100 km =
    0.007m³ / 100,000 m =
    0.000007 m² =
    0.07 mm²

    The question what this area represents is left as an exercise to the reader.

    Bonus trivia: The newest SI prefixes are only 2 years old:

    • quetta (Q) = 1030
    • ronna (R) = 1027
    • ronto (r) = 10-27
    • quecto (q) = 10-30
