    Myria for ##10^4## and dimi for ##10^{-4}## have been in use in France until the middle of the 20th century.
    Today we use potentials of ##10## until ##1000## and then potentials of ##1000## which makes sense to cover the different orders we face. For everyday life we still have the small ones plus some special terms like hectares or acres.
