# what is the relationship between kg and cubic meter?

NO relationship.

The base units for metric are:

metre for length ((a cubic meter is 3D of length)) kilogram for mass second for time ampere for electromagnetism kelvin for temperature candela for luminous intensity mole for quantity

Then mix and match for derived units

And apply prefixes, like milli, micro, kilo, mega

Both are metric measure. If you know one and the specific gravity of the material, you can figure out the weight.

10cm x 10cm x 10cm= 1000cu cm or 1 Liter.

1 Liter of water weighs 1000grams or 1 kilogram or 2.2lbs

knowing that you can figure out how much weight there is in a cu. M 1 M=100cm

Doing the rest= 100x100x100=1000000g/1000=1000kg or 2200ibs(long tonne)

You have much more problems when figuring out the weight of the water in a swimming pool using inches and pounds because they have no relationship.

it is the unit of density as kg denotes mass and cm^3 denotes volume

if one takes a cube container and fill it up with water , the volume of water is measured in cubic meter. The mass weight of the water is measured as a kilogram mass. The water is subject to gravity pressure and temperature. when temperature rises the water is less dense. That means a different temperature and pressure the ratio of mass to volume changes.This means there are less atoms per unit volume.This is denoted by a term called"density.".

The Earth as a Globe is not a cube. It can be considered as sitting in a cube of space. The ratio of the volume of the earth to the volume of space is approx 52% of the total volume of space.

In Electrical circuits we have a certain amount of Power flowing thru a conductor area.

In this case we have Current per unit Area as the Power Density.

The relationship is mass = volume * DENSITY where density is a property of whatever material you are dealing with.

For pure water it is about 1000 kg/m^3 other materials have densities from about 1 kg/m^3 ( air) up to 20000 kg/m^3

m = V * ρ

Mass equals volume times density.

if density is in units of kg per cubic meter, then an object of volume V will have a mass of V * ρ

There I no relationship. A kg is a unit of mass. A cubic meter is a unit of volume.

Mass = volume * density.

Make sure to use compatible units.

None! At ordinary T and p, the mass of a cubic meter of water is very close to 1000 kg, but if you substitute any other material, you are not going to get a "nice" number.
