Convert Square decimeter (dm²)

To achieve the desired result as quickly as possible, it is best to enter the value to be converted as text, for example or '21 dm2 to nm2' or '21 dm2 into nm2' or simply '21 dm2':

In most cases, the word 'to' (or '=' / '->') can be omitted between the names of the two units, for example '21 dm2 nm2' instead of '21 dm2 to nm2'.
In the abbreviations for 'square' and 'cubic', the '^' character can be omitted from '^2' and '^3'. Square centimetres can therefore be written cm2 instead of cm^2.
The basic operations of arithmetic: division (/, :, ÷), exponent (^), brackets, addition (+), pi (π), square root (√), subtraction (-) and multiplication (*, x) are all permitted at this point
Instead of the Greek letter 'µ' (= micro), a simple 'u' can be used, for example uPa instead of µPa.
Instead of 2.01 x 10^5, 2.01e5 can be written. The 'e' stands for 'exponent'.

or: Using the calculator with the selection lists

Choose the right category from the selection list, in this case 'Area'.
Next enter the value you want to convert.
From the selection list, choose the unit that corresponds to the value you want to convert, in this case 'Square decimeter [dm²]'.
The value will then be converted into all units of measurement the calculator is familiar with.

Use the full power of this unit converter to convert dm2

With this calculator, it is possible to enter the value to be converted together with the original measurement unit; for example, '9 Square decimeter'. In so doing, either the full name of the unit or its abbreviation can be usedas an example, either 'Square decimeter' or 'dm2'. Then, the calculator determines the category of the measurement unit of measure that is to be converted, in this case 'Area'. 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.

Instead of '√4' you can also write 'sqrt 4'.
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, '44 * 93 dm2'. But different units of measurement can also be coupled with one another directly in the conversion. That could, for example, look like this: '45 Square decimeter + 94 Square decimeter' or '43mm x 92cm x 42dm = ? cm^3'. The units of measure combined in this way naturally have to fit together and make sense in the combination in question.
If required, the result can be rounded to a certain number of decimal places wherever it makes sense.
The mathematical functions exp, sqrt, acos, pow, asin, cos, sin, atan and tan can also be used. Example: tan(90°), sin(90), cos(pi/2), 2 exp 3, atan(1/4), sin(π/2), 3 pow 2, asin(1/2), sqrt(4) or acos(1)
Instead of '4^3' you can also write '4 exp 3' or '4 pow 3'.
If a check mark has been placed next to 'Numbers in scientific notation', the answer will appear as an exponential. For example, 3.222 222 192 9×1020. For this form of presentation, the number will be segmented into an exponent, here 20, and the actual number, here 3.222 222 192 9. 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 3.222 222 192 9E+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: 322 222 219 290 000 000 000. Independent of the presentation of the results, the maximum precision of this calculator is 14 places. That should be precise enough for most applications.
