### 4/5 — Doesn't have mil conversion

*2020-01-19*

I like the app but it doesn't convert to mils (which isn't a big deal but would be nice to have)

Also, it would be nice to have the display concert a given unit to more than 1 equivalent unit. I'm constantly converting between mils, inches, and mm all day long and need a tool that can give me quick results so when I put in 1 unit, I can see the equivalent two converted units. 

This tool is easy to use in that there isn't a lot of clutter and buttons and wheels on the screen that take time going thru. The simple interface makes it nice to use.

### 5/5 — Contrary to another review, this App does what it says it will do.

*2019-11-06*

Someone wrote a negative review here claiming this App does not convert decimal to fraction. It does but not in a dedicated and/or formally displayed way.  In order to see the conversion, you have to look in the worksheet where the end calculation is rounded to the fraction you've set the App to. I suppose it would be nice to have a dedicated display for this conversion, but it is not a deal breaker for getting and using this very functional and simple App.

### 1/5 — App is a Liar (Not as advertised)

*2019-05-25*

In the app store, in clearly states metric decimals will be converted to fractional Imperial units; eg, millimeters to fractional inches. Getting a decimal inch result is completely useless; you now have to find another calculator to convert decimal inches to fractional inches in order to use the converted amount. This app is not worth it, do not buy. There are many other FREE apps that do the exact same thing, and do not lie about their capabilities.

### 5/5 — Delivers as promised

*2019-03-14*

I have been looking for a calculator to convert imperial fractions to millimetres and this does this and more. I had already wasted twice the purchase cost on an another app that only converted fractions to a imperial decimal equivalent but not to millimetres so l am very pleased with this app

### 5/5 — Exactly what I needed

*2017-05-07*

I've found that most other conversion apps are cluttered with so many different types of units that they become annoying and I reach for my calculator.  This one converts inches to metric, metric to inches, decimal or fraction.  Simple....no clutter....love it.
