Some facts

  • The basic unit for expressing dimensionless quantities in the SI system is one uno:
    1U=1=11=100%1 U = 1 = \frac{1}{1} = 100 \%
  • In practice, however, SI units are rarely used for this purpose in favor of traditional units, often developed for the needs of a given field, e.g.:
    • percent (/00\mathrlap{\it{/}}{^0}_{\,0}) - equal to one hundredth of the whole (1100\frac{1}{100}), used in many fields such as finance (e.g. interest rate on deposits) or chemistry (e.g. concentration of solutions), you can find more about percentages in our other calculator: Percentage
    • permile (/000\mathrlap{\it{/}}{^0}_{\,00}) - equal to one thousandth of the whole (11000\frac{1}{1000}), used, for example, when determining the alcohol concentration in the blood,
    • basis point (/0000\mathrlap{\it{/}}{^0}_{\,000}) - equal to one ten-thousandth of the whole (110000\frac{1}{10000}), used in economics and accounting,
    • pip (percentage in point) - equal to one ten-thousandth of the whole (110000\frac{1}{10000}), used to determine the change in exchange rates on foreign exchange markets (so-called FOREX),
    • tick size - equal to one thirty-second (132%\frac{1}{32}\%) or one six-quarter (164%\frac{1}{64}\%, so-called tick plus) of the percent, used when determining fluctuations bond rates on the US stock exchange,
    • ppm (parts per million) - equal to one millionth of the total (11000000\frac{1}{1000000} ), used in the natural sciences to determine very small concentrations, analogous units are also used such as ppb (parts per billion), ppq (parts per quantillion) etc.

How to convert

  • Enter the number to field "value" - enter the NUMBER only, no other words, symbols or unit names. You can use dot (.) or comma (,) to enter fractions.
    • 1000000
    • 123,23
    • 999.99999
  • Find and select your starting unit in field "unit". Some unit calculators have huge number of different units to select from - it's just how complicated our world is...
  • And... you got the result in the table below. You'll find several results for many different units - we show you all results we know at once. Just find the one you're looking for.
