Repeal laws relating to European Weights and Measures.
We now have a hybrid system of measurements, we buy petrol in litres but measure distance in miles, economy figures are posted in miles per gallon requiring a calculator and conversion tables to check. Beef is sold by the kilo but most children recognise and ask for a "quarter ponder". Although the distance to the next town is in miles the distance to the next junction is in metres.
European law allows you to ask for a 6 foot fencing panel but not an 8 foot fencing post. You can buy a pint of beer or milk but buy a 75cl bottle of wine or a pub spirit measure of 25cc.
A rugby union field now has 5, 10 and 22 metre lines but the football field still has a 6 and 18 yard box. (Even the French have an 8 foot by 8 yard goal).
We weigh ourselves in stones or kilos measure our height in feet or metres and our temperature in Celsius or Fahrenheit.
Why does this idea matter?
If we do not decide how to tackle this mess now it will be with us for generations.
