From Robert Thurstans, De Montfort University

Cailliau is incorrect in believing that the metric system will die out. The
British units of length and mass are now officially defined in terms of SI
units—so, for example, 1 inch is defined as exactly 2.54 centimetres.

SI units are now used in all countries of the world, except the US, and even
there all new physics textbooks are in SI units. When this is the case the
general populace cannot be far behind.
