What is standard pronunciation?
1. /ouə/
2. /ɑ:/
/ɑ:(r)/ or /aʊə(r)/ in BrE.
Context is always important; labelling is rarely important.
Does it sound the same as hour?
Yes, but that doesn't help, because some people pronounce that as /ɑ:(r)/. Most speakers of standard BrE pronounce the diphthong of hour, flower, power, differently from the vowel of are, far, par.

Thank you!
Many thanks for the links. I pronounce it same as "hour" myself but it is always good to know of the other different pronunciations that exist!
