**Convert** **Energy**:

With this calculator, it is possible to enter the value to be converted together with the original measurement unit; for example, '943 Attojoule'. In so doing, either the full name of the unit or its abbreviation can be usedas an example, either 'Attojoule' or 'aJ'. Then, the calculator determines the category of the measurement unit of measure that is to be converted, in this case '**Energy**'. After that, it converts the entered value into all of the appropriate **units** known to it. In the resulting list, you will be sure also to find the conversion you originally sought. Regardless which of these possibilities one uses, it saves one the cumbersome search for the appropriate listing in long selection lists with myriad categories and countless supported **units**. All of that is taken over for us by the calculator and it gets the job done in a fraction of a second.

#### Mathematical expressions

Furthermore, the calculator makes it possible to use mathematical expressions. As a result, not only can numbers be reckoned with one another, such as, for example, '(67 * 34) aJ'. But different **units** of measurement can also be coupled with one another directly in the conversion. That could, for example, look like this: '34 Attojoule + 1 Attojoule' or '1mm x 67cm x 34dm = ? cm^3'. The **units** of measure combined in this way naturally have to fit together and make sense in the combination in question.

#### Mathematical functions

The mathematical functions sin, cos, tan and sqrt can also be used. Example: sin(π/2), cos(pi/2), tan(90°), sin(90) or sqrt(4).

#### numbers in scientific notation

If a check mark has been placed next to 'Numbers in scientific notation', the answer will appear as an exponential. For example, 1.884 271 587 791 4×1020. For this form of presentation, the number will be segmented into an exponent, here 20, and the actual number, here 1.884 271 587 791 4. For devices on which the possibilities for displaying numbers are limited, such as for example, pocket calculators, one also finds the way of writing numbers as 1.884 271 587 791 4E+20. In particular, this makes very large and very small numbers easier to read. If a check mark has not been placed at this spot, then the result is given in the customary way of writing numbers. For the above example, it would then look like this: 188 427 158 779 140 000 000. Independent of the presentation of the results, the maximum precision of this calculator is 14 places. That should be precise enough for most applications.- Convert Attojoule (aJ)
