# Energy unit Converter online

With this calculator, you can enter a value to convert with the original unit of measure, for example, '849 Joule'. You can use either the full name of the unit or its abbreviation, for example, 'Joule' or 'J'. After entering the unit of measure to be converted, the calculator determines its category, in this case 'Energy'. It then converts the entered value to all the relevant units that it knows. In the list of results you will surely find the converted value you need. Alternatively, the value to be converted can be entered as follows: '30 Joule per Kilowatt-hour', '9 J -> kWh' or '38 J = kWh'. In this case, the calculator will also immediately understand the unit of measurement to convert the original value. No matter which of these options is used, it eliminates the need for complex searching of the desired value in long selection lists with countless categories and countless supported units. All this for us makes a calculator that copes with its task in a fraction of a second.

In addition, the calculator allows you to use mathematical formulas. As a result, not only numbers such as '(89 * 1) J'are taken into account. You can even use multiple units directly in the conversion field. For example, such a combination might look like: '849 Joule + 2547 Kilowatt-hour' or '25mm x 36cm x 59dm = ? cm^3'. Combined in this way the units of measurement, of course, must correspond to each other and make sense in a given combination.

If you check the box next to the 'Numbers in scientific record' option, the answer will be presented as an exponential function. For example, 9,235 209 915 959 6×1031. In this form, the representation of a number is divided into an exponent, here 31, and the actual number, here 9,235 209 915 959 6. Devices that have limited number display capabilities (such as pocket calculators) also use the 9,235 209 915 959 6E+31 method of recording numbers. In particular, it makes it easier to view very large and very small numbers. If the check box is not selected in this cell, the result is displayed using the normal number recording method. In the example above, it will look like this: 92 352 099 159 596 000 000 000 000 000 000. Regardless of the presentation of the result, the maximum accuracy of this calculator is 14 decimal places. This accuracy should be sufficient for most purposes.
