Another great Google feature: currency conversion. Just Google for an amount with a given currency designation “in” another currency designation.
For example, 15.25 USD in GBP, or get a simple conversion rate with USD in GBP. More verbose forms are supported as well, such as currency of India in Chinese money or 22.1 Indian rupees in Japanese money. Some currency signs are supported, such as US$15.24 in Australian money or simply $15.24 in Danish money.
