Useful once you know how to operate it

The is a good conversion app once you learn how to operate it. It would help if the graphic labels included text that explained what each key is. It would also help if there was a set of prompts on each page such as: step 1 select category then push arrow, step 2 select from measuring unit- enter amount and to measuring unit-enter amount.

Comprehensive, plus customizable for simplicity.

This conversion calculator has every conversion you can conceive, only a few of which you are likely to ever need. As delivered, the program shows them ALL(!), which can be overwhelming to those who take only a superficial look.

However, if you bother to learn the options, it is easy to ‘turn off’ the obscure categories so they do not clutter the main menu.
- For example; I need ‘density’ conversions, but will never use ‘radiation’ conversions.
Also, within each category, you can to ‘turn off’ the little-used units within each conversion category.
- For example; In ‘density’, I regularly convert gm/cm3 to lbs/ft3, but never convert them to grains/km3 (!)

An EXCELLENT tool. It’s hard to imagine how it could be made better without ‘dumbing it down’ at the cost of lost capability.

To those who say ‘too complicated’, I say: “No conversion tool can be BOTH comprehensive and simple ‘out of the box’.” The authors have given us both, PROVIDED you will take a little time to customize it for your own purposes.

Takes some figuring out

I really like this app as I am always converting something for projects. It’s taken me a while to get the hang of it and still don’t feel real confident that I know how it’s supposed to work. I still stumble around when trying to figure out something new but when I finally figure out the thought process behind this I really like using it. This app will convert so much more than I will ever use! Very thorough.
