[iOS] Amount is a delightful conversion calculator that works for all types of unit conversions

AmountThe other day I entered into a petty dispute with a classmate of mine regarding whether there are 1000 or 1024 megabytes in a gigabyte. To bring the silly discussion to an end, I whipped out my phone and brought up Amount. Bringing the argument to a  halt, I announced not only the amount of megabytes, but how many bits, bytes, kilobytes, petabytes, and terabytes can hang out in a gigabyte.

What is it and what does it do

Main Functionality

Amount is a conversion calculator with a wide variety of categories. The categories break down into units that can all be converted to and from each other. To convert a number you either plug it in on the title screen or inside a category, then tap the unit you are converting from, and every unit in the category will become converted. To edit units in each category either shake the devise, or tap the name of the category at the top of the screen. To check previous conversions there is an icon at the top left of the initial screen.

Pros

  • Supports conversions of: angles, area, cooking, currency, energy, length, power, pressure, speed, storage, temperature, time, volume and weight
  • Clean looking interface
  • No ads clustering up the screen
  • Currency converter is updated frequently
  • Copy units directly from the app

Cons

  • Interface is confusing at first glance
  • Lack of customization

Discussion  

Amount (1)When I first started the app I was impressed by how neat and simple the it was; the lack of ads was nice. The actual conversion was a little confusing at first as it works differently than most the conversion calculators I have used before. In the typical converter you would type in a number, click on a drop-down list,  pick the unit you have, and then the one you want. Although, with Amount, you type the number, select the unit out of the list, then every other unit on the page converts. So instead of viewing only one unit to one unit you see the entire category of units convert to one. So, viewing how many feet are in a mile compared to how many are in a kilometer is a much easier task.

I find the variety of categories overly pleasing. They range from simple day to day conversions to more complex and specified ones. I wish I had this app while taking physics, as most of the conversions I did by hand are on here. The currency category is great for people who travel a lot, whether it be for work or enjoyment, as it has all the major world currencies, and is updated in real time. Allowing you to calculate exactly how much foreign currency you will receive before you actually exchange your money.

There are little issues I have with this app. The main concern is the low level of customization. I wish to arrange units so the ones I convert the most are in close proximity. The only way to achieve that as of now it to hide all the other units. It would also be nice to change the color scheme because the entity of the app is a dull white.

Conclusion and download link

Overall, Amount is quite a handy app. It is quick, easy to use, and straight forward. I have not experienced a single bug or any kind of glitch. I would recommend it for anyone who routinely preforms conversions in any sort of field.

    For RAM, a megabyte consists of 1024 (2^10) kilobytes, therefore, (1024×1024) or 2^20 8-bit bytes (9bits if there is a parity bit, but only 8 are useable for data). A gigabyte of RAM is 1024 times that, eg, 10^30 bytes.

    This is not disputable.

    For historical reasons, long after that definition was well established, some hard drive manufacturers started using the word “megabyte” to improperly mean exactly one million bytes. Other HD manufacturers started picking it up, and by now FOR DISKS, megabyte, gigabyte, and terabyte are commonly used do mean exactly one million, one billion, and one trillion respectively. Geeks like me made such a stink about that erroneous use of the terms that it is rare that they do not also designate that they are lowballing their hyped number by making sure the consumer knows their dastardly definition of the word.

    For other items like memory sticks, and SSDs, the meaning of those three have not been well established, but it appears that SSDs are likely to be looked at as HDs. However, since there is always at least 7% more memory than (so far) printed as “existing” on an SSD box so “bad blocks” can be transparently covered without “reducing” the figure, that meaning is in flux at present.

    I have never, not once, seen any manufacturer designate kilobyte, megabyte or gigabyte of actual RAM to mean exactly thousand, million or billion instead of 2^10, 2^20 or 2^30.

    So, long and short of it, is that current usage is that gigabyte has different meanings depending on whether it is applied to RAM or Hard Drives.
