Convert Distance

To achieve the desired result as quickly as possible, it is best to enter the value to be converted as text, for example '213 cm to am' or '213 cm into am' or simply '213 cm':

• In most cases, the word 'to' (or '=' / '->') can be omitted between the names of the two units, for example '213 cm am' instead of '213 cm to am'.
• Instead of 1.86 x 10^5, 1.86e5 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.
• 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: subtraction (-), brackets, square root (√), multiplication (*, x), addition (+), division (/, :, ÷), exponent (^) and pi (π) are all permitted at this point

or: Using the calculator with the selection lists

1. Choose the right category from the selection list.
2. Next enter the value you want to convert.
3. From the selection list, choose the unit that corresponds to the value you want to convert.
4. The value will then be converted into all units of measurement the calculator is familiar with.

Round the result to a certain number of decimal places

If required, the result can be rounded to a certain number of decimal places wherever it makes sense.

Mathematical expressions

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, '95 * 87 cm'. But different units of measurement can also be coupled with one another directly in the conversion. That could, for example, look like this: '12 Centimeter + 4 Centimeter' or '79mm x 71cm x 63dm = ? cm^3'. The units of measure combined in this way naturally have to fit together and make sense in the combination in question.

Mathematical functions

The mathematical functions sqrt, tan, exp, pow, sin, acos, cos, atan and asin can also be used. Example: atan(1/4), 2 exp 3, sqrt(4), sin(90), acos(1), sin(π/2), tan(90°), cos(pi/2), 3 pow 2 or asin(1/2). Instead of '4^3' you can also write '4 exp 3' or '4 pow 3'. Instead of '√36' you can also write 'sqrt 36'.

Numbers in scientific notation

If a check mark has been placed next to 'Numbers in scientific notation', the answer will appear as an exponential. For example, 5.097 481 435 094 4×1020. For this form of presentation, the number will be segmented into an exponent, here 20, and the actual number, here 5.097 481 435 094 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 5.097 481 435 094 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: 509 748 143 509 440 000 000. Independent of the presentation of the results, the maximum precision of this calculator is 14 places. That should be precise enough for most applications.
