http://news.bbc.co.uk/1/hi/health/8455252.stmThe term "units of alcohol" should be scrapped in favour of centilitres of pure alcohol, the Tories have said.
The party said there was confusion over units and the UK should adopt specific measures, as much of Europe does, to help encourage safer drinking.
They also called for extra information to be given on labelling, including calorie content, as part of a voluntary agreement with the drinks industry.
But the proposals were given a lukewarm response by campaigners.
Alcohol Concern said it was in favour of more information being given, but added many people were beginning to get a grasp on units.
A spokeswoman added: "Allowing the industry to regulate itself is like a chocolate teapot. You need mandatory regulation."
The proposals were part of a series of policies - many already announced - which were published in the Conservative Party's new public health strategy.
Professor Alan Maryon-Davis, president of the UK Faculty of Public Health, said: "Changing to centilitres would be a big mistake and undo 30 years of public education about units of alcohol.
"The best way to tackle confusion is to have mandatory standardised labelling. It's time to stop pussyfooting around with the alcohol industry."
I think this is a terrible idea. Many people are familiar with the units system and I don't think it would be any more meaningful to people to say their can of lager has 20cl of alcohol, than to say it has two units. It isn't broken, don't fix it.
