Convert Calories to Kilojoule (cal to kJ)

To achieve the desired result as quickly as possible, it is best to enter the value to be converted as text, for example '118 cal to kJ' or '118 cal into kJ' or simply '118 cal':

In most cases, the word 'to' (or '=' / '->') can be omitted between the names of the two units, for example '118 cal kJ' instead of '118 cal to kJ'.
Instead of the Greek letter 'µ' (= micro), a simple 'u' can be used, for example uPa instead of µPa.
Instead of 1.36 x 10^5, 1.36e5 can be written. The 'e' stands for 'exponent'.
The basic operations of arithmetic: subtraction (-), multiplication (*, x), square root (√), division (/, :, ÷), pi (π), addition (+), brackets and exponent (^) are all permitted at this point
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.

or: Using the calculator with the selection lists

Choose the right category from the selection list, in this case 'Energy'.
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 'Calories [cal]'.
Finally choose the unit you want the value to be converted to, in this case 'Kilojoule [kJ]'.

Use the full power of this unit converter to convert cal to kJ

With this calculator, it is possible to enter the value to be converted together with the original measurement unit; for example, '106 Calories'. In so doing, either the full name of the unit or its abbreviation can be usedas an example, either 'Calories' or 'cal'. Then, the calculator determines the category of the measurement unit of measure that is to be converted, in this case 'Energy'. 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: '34 cal to kJ' or '67 cal into kJ' or '1 Calories -> Kilojoule' or '67 cal = kJ' or '34 Calories to kJ' or '1 cal to Kilojoule' or '34 Calories into Kilojoule'. 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 tan, acos, sin, pow, exp, cos, asin, atan and sqrt can also be used. Example: 3 pow 2, asin(1/2), tan(90°), sqrt(4), acos(1), atan(1/4), cos(pi/2), 2 exp 3, sin(π/2) or sin(90)
Instead of '4^3' you can also write '4 exp 3' or '4 pow 3'.
If required, the result can be rounded to a certain number of decimal places wherever it makes sense.
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, 1.884 271 587 791 4×1020. For this form of presentation, the number will be segmented into an exponent, here 20, and the actual number, here 1.884 271 587 791 4. 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 1.884 271 587 791 4E+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: 188 427 158 779 140 000 000. Independent of the presentation of the results, the maximum precision of this calculator is 14 places. That should be precise enough for most applications.
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, '67 * 34 cal'. But different units of measurement can also be coupled with one another directly in the conversion. That could, for example, look like this: '34 Calories + 1 Kilojoule' or '1mm x 67cm x 34dm = ? cm^3'. The units of measure combined in this way naturally have to fit together and make sense in the combination in question.
