Length is the measurement of the extent of something along its greatest dimension. The SI unit of volume is the cubic meter (m 3 ), which is the volume occupied by a cube that measures 1 m on each side. This very large volume is not very convenient for typical use in a chemistry laboratory.

Thereof, what is unit chemistry?

A unit is any standard used for making comparisons in measurements. Unit conversions allow for measurements of a property that have been recorded using different units—for instance, centimeters to inches.

Additionally, what is short form of decimeter?

Decimeter is a metric unit used to measure length or distance. Decimeter is abbreviated as dm.

What are the 7 basic units of measurement?

The seven SI base units, which are comprised of:
  • Length - meter (m)
  • Time - second (s)
  • Amount of substance - mole (mole)
  • Electric current - ampere (A)
  • Temperature - kelvin (K)
  • Luminous intensity - candela (cd)
  • Mass - kilogram (kg)

What is SI unit of density?

The SI unit of kilogram per cubic metre (kg/m3) and the cgs unit of gram per cubic centimetre (g/cm3) are probably the most commonly used units for density. One g/cm3 is equal to 1000 kg/m3.
