Cubic metre
The cubic meter is the unit of measure for the volume in the International System of Units (SI).
- Unit symbol: m3
- Symbols of the volume: V
One cubic meter or ' meters high 3' corresponds to the volume ( volume) of a cube with edge length 1 meter.
1 cubic meter is 1000 cubic decimeter (including 1,000,000 cubic centimeter) and since the 12th CGPM (1964 ) also exactly 1,000 liters (or 1 kiloliter ). One cubic meter of water has about the mass 1 metric ton (t ), at a temperature of 277.13 K (3.98 ° C) and standard atmospheric pressure of 101325 Pascals ( 1013.25 hPa = 101.325 kPa), there are 999.975 kg.
Different spellings
In addition to the unit m3, see eg architects or abbreviations cbm CBM use, rare cm, because the risk of confusion with the length units of centimeters.
When working on the computer modern word processing programs allow the entry of 3 as superscript number. Some typesetting programs or equation editors require you to enter in the form m ^ 3
Common variations of the unit cubic meter
By setting an appropriate SI prefix between cubic and meter, you can also define other measures of volume. The intent is there, according to the International System of Units (SI ) is set directly in front of the base unit.
Cubic millimeter
The cubic millimeter ( unit symbol: mm3 ) is an SI unit of volume ( see also: measure ). One cubic millimeter or ' millimeters high 3 ' corresponds to the volume of a cube with 1 mm = 0.1 cm edge length. 1 cubic millimeter is exactly one-millionth of a liter ( 0.000001 liters), which is exactly 1 microliter ( ul). This volume of water weighing about 1 milligram ( mg). It is 1000 mm3 = 1 cm3.
Cubic centimeters ( milliliters)
The cubic centimeter ( unit symbol: cm3 of batteries: cc ) is an SI unit of volume. A cubic centimeter or inches high 3 'corresponds to the volume of a cube with 1 cm = 10 mm edge length. With the proliferation of computers, the problem occurred that the superscript, 3 'could not be shown, therefore, have been and are still partially the Behelfsschreibungen, cm3 ', cm ^ 3 ',' cm ** 3 ' or regarded as outdated, cc 'is used. 1 cubic centimeter is one one-thousandth of a liter (0.001 l or L), or 1 milliliter ( ml). This amount of water weighing about 1 gram ( g).
From the English abbreviation "cc" for cubic centimeter, which is not permitted, however, in the SI system is derived.
Cubic decimeters (liters)
The cubic decimeter ( unit symbol: dm3 ) is a measure of volume. A cubic decimeter or " decimetres high 3 " describes the volume of a cube with an edge length decimeter. An equivalent name for the cubic decimeter is the ( obsolescent: the ) since 1964 connected to the SI unit system liter. Even the descriptions of " cdm ", " dm ^ 3" and " dm ** 3 " have been developed, but are purely formally by the SI system wrong, although it is quite common, the sign as ³ ^ to write 3 if it is not available.
During the meters and with him also cubic meters and cubic decimeter more or less over the length of certain items ( Erdmeridian, standard meter ) was defined, which the cubic decimeter long time not quite the same liter collection found by other means in the volume measures. His definition was based until 1964 on the volume of one kilogram of water under certain environmental conditions. Only on the 12th CGPM the liter measure was attached via the cubic decimeter to meter definition.
Cubic decameter
The cubic decameter ( unit symbol: dam3 ) is a measure of volume. One cubic decameter corresponds to the volume of a cube with edge length of 10 meters. One cubic decameter are 1,000 cubic meters, or 1 million liters.
Cubic hectometres
The cubic hectometres ( unit symbol: hm3 ) is a measure of volume. A cubic hectometres corresponds to the volume of a cube with an edge length of 100 meters. A cubic hectometres are 1 million (106 ) cubic meters.
Cubic kilometers
A cubic kilometer ( unit symbol: km3 ) or ' kilometers high 3 ' corresponds to the volume of a cube with an edge length of 1 kilometers. A cubic kilometer of one billion (109 ) cubic meters.
