### 1/5 — useless

*2018-10-05, version 1.0.0*

unable to enter numbers

### 1/5 — Inaccurate

*2018-04-27, version 1.0.0*

So when u convert 170 lbs (or any weight) to kilograms you get 77.11 which is accurate! HOWEVER when u go backwards from (also any weight) 77.11 kilograms to lbs you get 172,726.40 kg WHICH IS NOT CORRECT WHEN you start from kilograms and convert to lbs it is totally INACCURATE

### 1/5 — Wrong

*2018-01-03, version 0.3*

Why does it tell me that one centimeter equals 1.6 inches?

### 1/5 — Always 182 Celsius

*2017-06-17, version 0.3*

As the title says, the temperature section always says 182 Celsius. No idea why but it didn't help when I needed an app fast.

### 1/5 — Good thing it's free...

*2017-06-02*

My metric knowledge isn't very good but I know enough to know that this app is totally inaccurate. 
The interface is okay but whoever rated it more than 2 stars needs help.

### 1/5 — Bad conversion

*2017-05-17, version 0.3*

90 degrees Fahrenheit is not 194 Celsius.

### 1/5 — Does not work

*2017-02-03*

I've tried several times to convert 100 grams to ounces. It keeps giving the result of 45 ounces which makes no sense. Deleting the app.

### 1/5 — Garbage...

*2017-01-24, version 0.3*

Equations are wrong.

### 1/5 — Horrible

*2017-01-18*

Never get this app it is all wrong.  It is not correct!!!!!   I converted one centimeter to one meter and I got 3.5. The reel answer is 0.001. I got that number from online.

### 4/5 — Good conversion app

*2017-01-04*

Gets the basic conversions right. I hope the devs add more important units so that it can become my go-to conversion app in my phone. Long way to go before it becomes one of the best. Let's see what the updates bring in.
