Convert Square decameter to Square kilometer (dam² to km²)

To achieve the desired result as quickly as possible, it is best to enter the value to be converted as text, for example '129 dam2 to km2' or '129 dam2 into km2' or simply '129 dam2':

In most cases, the word 'to' (or '=' / '->') can be omitted between the names of the two units, for example '129 dam2 km2' instead of '129 dam2 to km2'.
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.
Instead of 1.38 x 10^5, 1.38e5 can be written. The 'e' stands for 'exponent'.
The basic operations of arithmetic: exponent (^), division (/, :, ÷), addition (+), multiplication (*, x), pi (π), square root (√), brackets and subtraction (-) 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.

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 decameter [dam²]'.
Finally choose the unit you want the value to be converted to, in this case 'Square kilometer [km²]'.

Use the full power of this unit converter to convert dam2 to km2

With this calculator, it is possible to enter the value to be converted together with the original measurement unit; for example, '117 Square decameter'. In so doing, either the full name of the unit or its abbreviation can be usedas an example, either 'Square decameter' or 'dam2'. 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. Alternatively, the value to be converted can be entered as follows: '36 dam2 to km2' or '74 dam2 into km2' or '4 Square decameter -> Square kilometer' or '71 dam2 = km2' or '39 Square decameter to km2' or '7 dam2 to Square kilometer' or '42 Square decameter into Square kilometer'. 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.

The mathematical functions acos, sqrt, exp, pow, asin, atan, sin, tan and cos can also be used. Example: cos(pi/2), sin(90), sqrt(4), sin(π/2), 2 exp 3, tan(90°), 3 pow 2, atan(1/4), acos(1) or asin(1/2)
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, '80 * 48 dam2'. 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 decameter + 13 Square kilometer' or '16mm x 83cm x 51dm = ? cm^3'. The units of measure combined in this way naturally have to fit together and make sense in the combination in question.
Instead of '4^3' you can also write '4 exp 3' or '4 pow 3'.
Instead of '√4' you can also write 'sqrt 4'.
If a check mark has been placed next to 'Numbers in scientific notation', the answer will appear as an exponential. For example, 2.087 222 203 228 5×1022. For this form of presentation, the number will be segmented into an exponent, here 22, and the actual number, here 2.087 222 203 228 5. 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 2.087 222 203 228 5E+22. 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: 20 872 222 032 285 000 000 000. Independent of the presentation of the results, the maximum precision of this calculator is 14 places. That should be precise enough for most applications.
If required, the result can be rounded to a certain number of decimal places wherever it makes sense.
