Convert Density

To achieve the desired result as quickly as possible, it is best to enter the value to be converted as text, for example '344 pg/l to pg/dl' or '344 pg/l into pg/dl' or simply '344 pg/l':

  • In most cases, the word 'to' (or '=' / '->') can be omitted between the names of the two units, for example '344 pg/l pg/dl' instead of '344 pg/l to pg/dl'.
  • 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 the Greek letter 'µ' (= micro), a simple 'u' can be used, for example uPa instead of µPa.
  • Instead of 1.64 x 10^5, 1.64e5 can be written. The 'e' stands for 'exponent'.
  • The basic operations of arithmetic: addition (+), square root (√), division (/, :, ÷), exponent (^), brackets, pi (π), multiplication (*, x) and subtraction (-) 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.
  5. Then, when the result appears, there is still the possibility of rounding it to a specific number of decimal places, whenever it makes sense to do so.

Mathematical functions

The mathematical functions tan, sqrt, sin and cos can also be used. Example: tan(90°), sqrt(4), cos(pi/2), sin(π/2) or sin(90).

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, '51 * 32 pg/l'. But different units of measurement can also be coupled with one another directly in the conversion. That could, for example, look like this: '89 Picogram per liter + 70 Picogram per liter' or '13mm x 93cm x 74dm = ? cm^3'. The units of measure combined in this way naturally have to fit together and make sense in the combination in question.

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, 3.054 479 972 204 2×1022. For this form of presentation, the number will be segmented into an exponent, here 22, and the actual number, here 3.054 479 972 204 2. 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 3.054 479 972 204 2E+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: 30 544 799 722 042 000 000 000. Independent of the presentation of the results, the maximum precision of this calculator is 14 places. That should be precise enough for most applications.
