Kilometres or miles? Dollars or Baht?
Unless the world becomes united under the banner of Planet Earth, each country will continue to use their own currency and unit of measurement. Until then, we just have to deal with the different standards and convert different currencies and measurements to something we are familiar with.
If you're using a Palm, Currency (excuse the pun) is what you need when you're going on a shopping spree. This excellent currency database and conversion utility allows you to view at a glance how much you have to fork out for that antique vase collection you eyed for so long, all in you own domestic currency. It even allows you to perform basic calculations! The best thing about it is that when you install the Currency Calculator Conduit, you can grab the latest exchange rate every time you Hotsync your Palm. Best of all, it's all free!
Pocket PC users don't have to feel left out because they have a similar utility in Conversions. This handy application lets you convert between different currencies and automatically updates the foreign exchange rate from the Internet.
If you're only familiar with the metric system, things can get a little confusing when you're on the road. When someone tells you that your destination is a mile away, they don't mean that it's a kilometer away. So to prevent you from incorrectly judging distances (and other unit measurements like Celsius and Fahrenheit for that matter), Palm users should load Converter while Pocket PC users can try out the Unit Converter. These freewares allow you to convert units of measurement painlessly.
