Convert Square kilometer to Hectare (km² to ha)

To achieve the desired result as quickly as possible, it is best to enter the value to be converted as text, for example '885 km2 to ha' or '885 km2 into ha' or simply '885 km2':

In most cases, the word 'to' (or '=' / '->') can be omitted between the names of the two units, for example '885 km2 ha' instead of '885 km2 to ha'.
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: exponent (^), pi (π), division (/, :, ÷), addition (+), multiplication (*, x), brackets, subtraction (-) and square root (√) are all permitted at this point
Instead of 1.92 x 10^5, 1.92e5 can be written. The 'e' stands for 'exponent'.
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 kilometer [km²]'.
Finally choose the unit you want the value to be converted to, in this case 'Hectare [ha]'.

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

With this calculator, it is possible to enter the value to be converted together with the original measurement unit; for example, '873 Square kilometer'. In so doing, either the full name of the unit or its abbreviation can be usedas an example, either 'Square kilometer' or 'km2'. 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: '90 km2 to ha' or '65 km2 into ha' or '85 Square kilometer -> Hectare' or '80 km2 = ha' or '75 Square kilometer to ha' or '70 km2 to Hectare' or '60 Square kilometer into Hectare'. 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 sqrt, sin, pow, cos, asin, tan, atan, exp and acos can also be used. Example: sin(90), acos(1), sin(π/2), sqrt(4), asin(1/2), 2 exp 3, 3 pow 2, cos(pi/2), tan(90°) or atan(1/4)
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, '35 * 30 km2'. 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 kilometer + 40 Hectare' or '25mm x 20cm x 15dm = ? 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 '√25' you can also write 'sqrt 25'.
If a check mark has been placed next to 'Numbers in scientific notation', the answer will appear as an exponential. For example, 4.412 222 182 071 ×1021. For this form of presentation, the number will be segmented into an exponent, here 21, and the actual number, here 4.412 222 182 071. 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 4.412 222 182 071 E+21. 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: 4 412 222 182 071 000 000 000. 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.
