Would £1,000 pounds spent in London buy similar or more than $1000 spent in NYC?

I know London is expensive on the factor that on average $1.60 is needed to buy £1.00



But what about after already taking that exchange rate into consideration



And saying simply, does £1.00 spent in Britain buy you more worth or less worth than $1 in NY?



In other words, is UK more than or less than 60% pricier than US?

Would £1,000 pounds spent in London buy similar or more than $1000 spent in NYC?
