Imperial measures of volume (liquid capacity)

Below is a list of imperial measures of volume and how they relate to each other.

  • 20 fluid ounces (fl oz) to 1 pint
  • 8 pints to 1 gallon.

If you are as old as me, you will have had to learn all of these conversions between units of measure! The United Kingdom was ‘decimalised’ in 1971 which meant that the UK changed from using money in bases of 12 and 20 (12 pence in a shilling, 20 shillings in a pound) to the current system of 100 pence in a pound. This change in the measurement units for money happened fairly quickly but metrication (the change from the imperial system to the metric system), which began officially in 1973, remains unfinished. Schools teach the use of metric units but also have to teach learners about imperial measures because there are still areas of public life where these are used. Examples include distance in miles, vehicle speeds in miles per hour (mph) and beer sold in pints.
