The [harebrained] proposal of Boris Johnson to return to so-called imperial measurements or units illustrates [beyond his usual flair for spinning out of yet-another-scandal] an all-too-common innumeracy of politicians (and possibly a lingering anti-French sentiment as metric units were introduced by the French Revolution), preferring to cater to their Brexit voters rather than realising the drawbacks and costs of a parallel system of measurements, as illustrated by the 1999 Orbiter crash. Does he plan to exit the Bureau International des Poids et Mesures as well?! Or does he expect an improvement in numeracy with the public using different bases (other than 10) at ounce once?!
