Preev.com is the best site for me because it is very simple and easy to use and it offers different fiats option like USD,AUD,CAD and other kind of currency in other part of the world.
Yeah everyone know it, but i noticed that some days before preev looks not working properly. Only USD and EUR was only working perfect to check the btc conversion. I suggest you to try with coindesk price chart. Here you could find the news about bitcoin and price conversion to any value.
