# Some facts

• The basic SI unit of amount of substance is one mole.
• One mole of substance contains the same number of molecules (or atoms in the case of free elements that do create molecules) as 12 grams of carbon isotope 12C.
• In one mole there is 6,022140857 (74) × 10 23 particles (atoms, molecules, ions, etc.). This number is often called Avogadro number:
$N_A = 6,022140857(74) \times 10^{23}$
• One mole of substance may correspond to different mass. For example, one mole of water weighs 18,01528 g, but one mole of carbon dioxide 44,01 g. The mass of one mole of substance is called molar mass and is substance specific. You can read more about molar mass (including molar masses of selected substances) visiting our another calculator: Molar mass.
• One mole of perfect gas under normal conditions (temperature 273K, pressure 1023 hPa) occupies a volume of 22.42 dm3. You can find more about the volume occupied by various gases in our another calculators: Molar volume of gases and Clapeyron's equation.

# 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.
