A personal favorite – Convert Any Unit Review

I got the free version to use at work when needing to convert metric measurements to English and back again. I liked it so much, I upgraded to the paid version, which I like even more. It saves units I've used as favorites automatically. If I'm just trying to impress someone by showing them how many millimeters in a light year or how many teaspoons in a bushel, favorites are easy to edit. It's useful in unexpected ways, like converting units used on TV so I get what they are saying. Edit: You can now round your answer to fractions, up to 1/64. There is a color palate if you want a different background. Adjustable font size in case you have vision issues. Plus a host of advanced options. For instance, if you are not American or just preferred British spellings, you can even switch to that. It's almost a shame I already rated this 5 stars, as I cannot give it a "raise."
