Convert units, currencies and timezones faster than you type. Start with the number, then type one or two letters and see the result. Use dedicated numpad to avoid switching keyboards. Forget digging through endless unit categories in urge to find the one you need (although you can do it when in adventure mood). If the number is in your clipboard, we’ll pick it up. We learn what you convert to make better guesses over time. We keep currency rates updated, but show you approximate values when offline. We support alternative spelling of many units. Type “45f”, get Fahrenheit converted to centigrade right away. Or maybe you meant feet to meters? We’ll show that, too. We know, by the way, that it’s natural to convert feet to meters, but miles to kilometers. Get timezones conversion and more units with in-app purchase. Or just show your support by upgrading :-)
