It's hard to imagine how many different values, let's say, for speed … and it's scary to imagine. But these indicators are not only related to each other, but also in different countries there are indicators that are also all related … Confused? To prevent this from happening, I advise you to download the application for iPhone “IM Unit Converter”, which will help you figure out what's what. First, it should be noted that the application has a very simple interface and is not overloaded with unnecessary functions. Only a converter of values and nothing else 🙂 A little, however, annoying constantly flying out advertising, but you can cope with this, you just need to disconnect the Internet connection. So, before us is the main menu, from which it is clear that the application is able to convert measures of such quantities as: distance, mass, volume, area, temperature, data, time, speed, power. Looking into one of the tabs (for example, distance), you can see that such a seemingly ordinary value has so many indicators: both a kilometer and a meter, and even, I'm not afraid of this word, angstroms (about a million times less than a millimeter)! And, of course, this is only one of the categories (or classifications), do not forget that many countries have their own generally accepted measures that are closely related. I suggest trying to convert, say, 12 kilometers. Here's what happened: The same can be done with other indicators – volume, mass, speed, time, and so on. In each case, we will get a quick, and most importantly quick result. By and large, that's all the app is capable of. But, even to admit, nothing else is needed. “IM Unit Converter” will be very useful for students, schoolchildren, specialists, and ordinary users iPhone. A very decent app.
