I've used Unit Converter for several years, both at home and in the office. While I use it mainly for mass and distance conversions, I occasionally use other conversions. It is very straight forward, with extremely useful features (swapping to/from, drop down boxes displaying a wide array of conversion types, drop down boxes for the many to/from options specific to each conversion type, and probably others that I have yet to try out). It's a terrific tool, and I highly recommend it.

Works great, lots of unit options, and the ads aren't overwhelming. Great app! I use this to figure out ratios for mixing household cleaners and such.
