Lord Parkinson made the embarrassing blunder amid reports that the Government will launch a consultation on the possibility of bringing back the Imperial Measures. Appearing on Sky News, the Arts Minister was first asked how many ounces there are in a pound – to which he incorrectly answered 14.
Host Kay Burley then asked, “If you order a pound of sausage, approximately how many grams of sausage do you get? 250, 350, 450 or 550?
Lord Parkinson, who studied at Cambridge University, chose the first answer, again incorrectly, before being asked which volume was greater – four pints or three litres.
“Three pints?” he has answered.
It comes after Downing Street insisted the Imperial measures are ‘universally understood’.
According to reports, the return to the imperial measure is not only motivated by Britain’s departure from the EU, but also to celebrate the Queen’s Platinum Jubilee.

Former defense minister Tobias Ellwood said the idea was nostalgic and not “the conservative thinking of a nation”.
He said: “There is not just concern over the conduct of Number 10’s behavior because it has broken trust with the British people, it is now about Number 10’s thinking, our policies.
“What we are seeing now is an approach to shore up and drive out a slice of the electorate with policies such as the return of Imperial Measures.
“There will be people in our party who will like this nostalgic policy in the hope that it will be enough to win the next election. But this is not the case.
“It is not the conservative thinking of a nation that is needed to appeal beyond our base.
“It’s a far cry from the inspiring and visionary progressive thinking we need.
‘And it’s part of a pattern that I fear micro-ads are getting more and more out there, which actually sows more discontent with more MPs.’
