  New calculla released ! Please go to calculla.com for the calculla v2. It's better, faster, more beautiful, redone for you in most modern technologies.
  Two cars related tables released today: Tire codes - speed ratings and Tire codes - load index
  This time 3 new calculators for fractions: Fractions: adding and subtracting, Fractions: 4 operations and Fractions: inverse (reciprocal). Each of them shows all sub-steps needed to compute common denominators, create improper fraction (if needed), reduce the fraction etc.

Volume (capacity)
Converter of volume units (also capacity units). Supports 110+ different units used over the world. Gallons, litres, cubic meters, pints, barrels and 100+ other !
Some facts
  • The volume is a measure of the space occupied by the body in three-dimensional space.
  • The basic volume unit in SI system is 1m3 (one cubic meter). However, it is rare used in everyday life. Most common units are - depending on region - liters and galoons.
  • The volume occupied by the body generally depends on external conditions (temperature, pressure). This fact must be taken into account, for example during the construction of bridges, where it is necessary to take into account the thermal expansion of metals.
  • the ideal gas state equation involves the volume occupied by the gas from its temperature and pressure. This equation is a good approximation to the behavior of real gases. The equation was formulated in the nineteenth century by Benoît Clapeyron. It takes the form: pv=nRT, where p is the pressure, v is volume, n is the number of moles of gas in the system, T is temperature, and R is the gas constant amounting to 8.314 J/(mol·K).
  • Volume of many bodies can be computed from their dimensions. Examples are:

    • Volume of a cuboid - V=a·b·h, where a, b are, respectively, the dimensions of the base, and h is his height.
    • Volume of a cone - V=1/3·S·h, where S is a field base of the cone, and h is its height.
    • Volume of a cylinder - V = πR2·h, where h is the height of the cylinder and R is a radius of the base.

  • Most formulas to compute volume can be derived using calculus.
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.
