Free Unit Converter is a measurement unit converter for Windows. It contains a list of measurement units and their values and you can calculate what a certain unit is in another unit by simply selecting it from the list. Although you can now get conversions for measurement units on the Internet, it is always good to have an offline app for your calculations, if you really need to some very often.
Free Unit Converter has a very basic interface, but it is filled with information. All the measurement units are divided into categories, such as Distance and Length, Mass, Fuel Economy, etc. By selecting a category, you narrow down the units to a specific field. For example, if you select Distance and Length, you can measure how many feet 1 meter is, or vice versa. There are lots of different units. The metrical system is present, but there are also units from the bible, from Japan, Thailand, Greece, etc. On the right of the screen, you will see all the measurement units listed under system (metric, British, Japanese, etc). This is useful for knowing the exact numbers of each measurement.
All in all, using this app is really easy. It has lots and lots of information. I would say that there is too much information on screen at all times. I would find it more intuitive if there was a drop-down menu or if I could hide all the units that I am not using. But that is just how I like it. The application works great!
