Google Hangouts - should all wifi calls be free?

[Pinmac1]

I am in the UK and have used Google Hangouts to call numbers in the USA over arrangements for my upcoming holiday. These are all shown as free calls. When I try to phone a UK landline it is shown as charging 1p per minute and for UK mobiles it is 3p per minute. I thought that wifi calls would be free? Why and how is it charging? I was hoping to use Hangouts while in the US to phone local numbers (restaurants etc) using wifi. Will this still be free? As you can tell, I haven't got the hang of Google Hangouts yet!

AFAIK, it's US (+1) number are free, anything else like UK(+44), China(+86), etc. you have to pay for.

Like @mikedt said, calls to the US, Canada, and Puerto Rico are free regardless of where you're calling from. All other destinations you have to pay.
