Universal converter free: Converts all units of measurement

By oWorld Software

Open iTunes to buy and download apps.


This converter is an application designed to efficiently convert units of measurement such as speeds, temperatures, time, weight and distances etc.! It will help you make a success of your cooking recipes, maths homework, etc.

An essential tool for your iPhone. Stop asking questions like:
"How many millilitres are there in a centilitre?"
"We still have 158 miles to go. How far is that is km?"
"The speed limit is 80 miles/h. How fast is that is km/h?"

The answer is in this application. Its purpose is simple: performing conversions and doing it so well... that you can’t live without it.

Conversion categories:
- Mass (7 units)
- Computer measurements (8 units)
- Speed (7 units)
- Volume (13 units)
- Distance (8 units)
- Time (7 units)
- Temperature (5 units)
- Shoe size

- And many mores !

Great little app

Having used this app for free for years I decided to pay for the non advert version.
It is a great little app.
And to anyone who says its not just cough up some money to support the developer. It's only the price of half a pint of Guiness and if you have the full app you can find out what a pint is in litres.


You are utterly worthless. To the people who ruined this app by making it unusable due to constant forcible advertisement videos which show up and play consecutively one after another with a 1 second gap between them, you have just destroyed your customer base. You clearly don't know what you're doing and in the process have lost thousands of users. There's plenty of other apps, better apps out there so congratulations for completely destroying your app.

I was told to pay after already paying!

I used this app for two years, every day actually; and I paid for it 1.9 years ago for the privilege of it being ad free, however today the app wouldn't work; so I re downloaded it to find that I have to pay again to have the add's removed?!

For some reason they want me to pay again to once again have the add's removed from an app I paid for nearly two years ago👎!

There is no way on earth that I would pay again for an app I've already purchased, and to try and make me do so is theft.

I'm not happy with this company's brazen attempt to unjustly grab my cash, and I will certainly avoid any app they produce in the future.

Deceitful, greedy, money hungry con artists; avoid them guys, pick a different app.
