There’s no shortage of online conversion tools out there, but Convert World gets an honorable mention for having a clean and intuitive interface. Everything’s right there on the landing page when you need it. Enter your units and watch as the conversion takes place instantly without the need for a page refresh. This thing is no lightweight either; have a special conversion need? They’ve probably got the tool you’re looking for. Plus, you gotta love their support for 28 languages, which is a pretty good sign of their committment to this extremely helpful tool. Thanks clubcreatif.
