Units is a really useful app that lets you easily convert from various units into lots of others.
Units can convert hundreds of units from 43 different categories including Speed, Time, Length, Volume, Area, Power, Temperature, Fuel Consumption, Clothing & Shoe Sizes and loads more!
Units is now a fully universal app with native support for iPhones, iPod touches and iPads.
As an added bonus, Units also has a built in ruler, for doing small, quick measurements when the need arrises.
Units Premium disables adverts and allows you to reorder both units and unit categories to suit your needs.
