Some facts

The basic unit for expressing dimensionless quantities in the SI system is one uno:

$1 U = 1 = \dfrac{1}{1} = 100 \%$
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 ( $\mathrlap{\it{/}}{^0}_{\,0}$ ) - equal to one hundredth of the whole ( $\dfrac{1}{100}$ ), 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 ( $\mathrlap{\it{/}}{^0}_{\,00}$ ) - equal to one thousandth of the whole ( $\dfrac{1}{1000}$ ), used, for example, when determining the alcohol concentration in the blood,
- basis point ( $\mathrlap{\it{/}}{^0}_{\,000}$ ) - equal to one ten-thousandth of the whole ( $\dfrac{1}{10000}$ ), used in economics and accounting,
- pip (percentage in point) - equal to one ten-thousandth of the whole ( $\dfrac{1}{10000}$ ), used to determine the change in exchange rates on foreign exchange markets (so-called FOREX),
- tick size - equal to one thirty-second ( $\dfrac{1}{32}\%$ ) or one six-quarter ( $\dfrac{1}{64}\%$ , 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 ( $\dfrac{1}{1000000}$ ), 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.
Examples:
- 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.
