Imperial Weights and Measures

Scales Ruler Jug

This website is dedicated to the memory of the British Imperial Weights and Measures. I had to learn these at school, as part of my "tables". They were printed on the back of our exercise books (with blank pages, where we did our written work). Click here for a modern replica. While metric measures are simpler, these old measures are still part of our language, and will always be part of our literature. Anyway, it will be hard for my generation to think naturally in anything else! I am happy to use metric units, yet it would be sad if these old units were forgotten. The U.S. Customary systems are similar to the British Imperial System, but I mention where they differ.

Please email me (Jo Edkins) with any comments or any errors that you spot. I would like to acknowledge the previous corrections, additions and improvements emailed to me by many people, who are helping to make this website what it is.

Some people may be interested to know whether Britain uses metric or Imperial units. This is not easy to answer! Legally, at the moment (2005), Britain is mostly a metric country. The Statutory Instrument 1995 No. 1804 says so. But it also specifies exceptions, such as
  • the use of the mile, yard, foot or inch for road traffic signs, distance and speed measurement
  • the use of the pint for dispensing draught beer and cider
  • the use of the pint for milk in returnable containers
  • the use of the acre for land registration
  • the use of the troy ounce for transactions in precious metals
However, many, if not most, British people continue to use Imperial units informally.
