**Convert** Attometre (am):

With this calculator, it is possible to enter the value to be **converted** together with the original **measurement unit**; for example, '666 Attometre'. In so doing, either the full name of the **unit** or its abbreviation can be usedas an example, either 'Attometre' or 'am'. Then, the calculator determines the category of the **measurement unit** of measure that is to be **converted**, in this case 'Distance'. 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, '(15 * 88) am'. But different **units of measurement** can also be coupled with one another directly in the **conversion**. That could, for example, look like this: '666 Attometre + 1998 Attometre' or '87mm x 15cm x 5dm = ? 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).
