# Convert Measurement Units / Unit-Converter

**Unit conversion** is anything but trivial:
Millimeter, centimeter, decimeter, meter, kilometer, miles, nautical
miles, foot, yard, inch, cubit, parsecs and light years. With all
these measurements distances can be calculated. And this is not even
close to all the possible measurements, rather only the most common
ones. In the case of areas (square meter, square kilometer, are, hectare,
Morgan, acre among others), Temperatures (degrees of Celsius, Kelvin,
Fahrenheit), Velocity (m/s, km/h, mph, knots, mach), weights (hundred
weight, kilogram, metric ton, US ton, imperial ton, pound among others)
and volumes (cubic meter, hectoliter, imperial gallon liquid, US gallon
liquid, US gallon dry, barrel among others) is not much better. To
complete the chaos the majority of these units also have subunits
and supra units (-> milli, centi, deci among others). In short: Chaos,
in which no one really seems to see clearly without the help of a
reference and varied forms of help.
A calculator for units of measurement like this one is perfect for unit conversion.

- Choose the right category from the selection list.
- Next enter the value you want to convert. The basic operations of arithmetic: addition (+), subtraction (-), multiplication (*, x), division (/, :, ÷), exponent (^), brackets and π (pi) are all permitted at this point.
- From the selection list, choose the unit that corresponds to the value you want to convert.
- Finally choose the unit you want the value to be converted to.
- Then, when the result appears, there is still the possibility of rounding it to a specific number of decimal places, whenever it makes sense to do so.

#### Utilize the full range of performance for this units calculator

With this calculator, it is possible to enter the value to be converted together with the original measurement unit; for example, '244 Attoweber'. In so doing, either the full name of the unit or its abbreviation can be usedas an example, either 'Attoweber' or 'aWb'. Then, the calculator determines the category of the measurement unit of measure that is to be converted, in this case 'Magnetic flux'. 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. Alternatively, the value to be converted can be entered as follows: '96 Attoweber to Femtoweber' or '1 aWb -> fWb' or '69 aWb = fWb'. For this alternative, the calculator also figures out immediately into which unit the original value is specifically to be converted. 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, '(46 * 64) aWb'. But different units of measurement can also be coupled with one another directly in the conversion. That could, for example, look like this: '244 Attoweber + 732 Femtoweber' or '47mm x 11cm x 21dm = ? cm^3'. The units of measure combined in this way naturally have to fit together and make sense in the combination in question.
