Unit Converter Pro HD.

It’s simple to use and has every converter I need

Being handy and useful, it’s one app that’s been on every iPhone I’ve had.

This App gives me the unit conversions for anything I have needed so far.

This is the best conversion app I have found.

I have used this converter for many years, mostly to inform me of hight and width of my plants at their mature growth. It works flawlessly! Love it!

Use it all the time in process controls engineering!

Works great and converts lots of different units.

Only works in horizontal mode. Not very intuitive to use.

It has never failed me when I want to convert measurements that are unfamiliar. Today I used it to convert millibars to inches of mercury in order to understand a weather report. It is perfect for those questions like “How many gallons of water does my back yard get when there’s 2” of rain?” It is one of the most valuable applications on my phone.
