As Boris Johnson's government reportedly wants us to start using imperial measurements again, it has launched a review on when and where they can be used. It is something being discussed ahead of the Queen's Jubilee, and while government insiders say it would coincide with celebrations for the monarch's 70 years on the throne, others believe it is an attempt to distract from partygate.

The British Imperial System is the traditional system of weights and measures used officially in Great Britain from 1824 until the adoption of the metric system beginning in 1965.
At the moment, traders must use metric measurements when selling packaged or loose goods - but they can use imperial measurements alongside them. A legal requirement to use metric measurements when selling packaged or loose goods was first introduced by the EU in 2000. The law states that imperial measurements can be displayed as well as metric ones - but cannot be more prominent.
Miles, feet and inches are all imperial units of length, but there are plenty more too. Ever heard of a fathom, a hand or a cubit? Test yourself to see how well you know (or remember) them.
