Convert meter cubic to kilogram

The weight depend on the material, temperature, g etc.

You will therefore not find a single parameter conversion tool.

Thanks,

the weight meter cubic of water

One cubic meter of water = 1000kg, for other materials multiply by the specific gravity, but as pointed out volume varies with temperature.

Regards JD.

If one is going to be specific:-

It is 1m³ of demineralised water @ 4⁰C ...........water's maximum density

Thats right mate.

Regards JD.

The units are dissimilar - cubic meter is volume while kilogram is mass. Now if you're talking about a specific material (aluminum, for example) and know the density (2.7 g/cm²) you can then calculate that a cubic meter of aluminum is 2700 kg. Of course, as Hendrik states, the density of each material varies with temperature, and every material has a unique density, so every conversion will be unique. However, you will not need to worry about 'g' unless you're converting to Newtons (or pounds).

w=vol x spec gravity

So, here comes the effect of gravity, when we are talking of weight. Thus the weight of a mass will be different at various locations on earth. More on poles and less on equator.

sorry ,

insted of density i typed spce gravity

That because they are measures of different properties. One is a measure of volume that is how much space it takes up. The other is a measure of weight.

If you had a Kg of gold and a Kg of feathers which would take up more space. If I then change the Kg of gold to a Kg of water the volume of water would be more than the gold but still a lot less than the feathers.

Why do you need to know this? Do you need to be very accurate or is this for a general every day use. I used to work in aquaculture and we would use the term "cube" for 1 cubic meter of water. Well more accurately we were reffering to flow rates so it was actually reffering to 1 cubic meter per hour but the reason I say is that when we wanted to know the weight of water at a certain place we just used 1 cube=1000kg. In practice we never needed to be any more accurate.

Mass of material (Kg) = Volume (m³) x Density (Kg/m³)

So to find the mass in (Kg), you have to multiply the volume in (m³) by density of material in (Kg/m³).

This is fundamental, the metric system for weight and volume is based on water.

More precisely;

Relation of volume and mass of water

Originally, units for volume and mass were directly related to each, with mass defined in terms of a volume of water. Even though that definition is no longer used, the relation is quite close at room temperature and nearly exact at 4 degrees C. So as a practical matter, one can fill a container with water and weigh it to get the volume, for example,

Wikipedia

m^3 is volum unit and kg is mass unit

The SI and English system have several fundamental units: Lenght, mass, time, temperature, etc. From these fundamental units, we get another units, area = LxL, Volume = LxLxL. The definition of density is d = m/V. This equation is the relationship between mas and volume. Therefore, the proper question shoul be: What is the volume of one kilogram of water, Using the equation and checking tables of density in function of temperature we have

m = V x d(t)

where m = the mass in Kg

V = Volume in M3

d = density in Kg/m3

For water density usually is given as 1 g/cm3 = 1000 Kg/M3. At different temperatures, multiply the density value by 1000 to get in Kg/M3.

It is important to know the difference between Kg(mass) and Kg (force) to avoid mistakes.

Hello,

In the metric system we have Mass in kg and Force in Newton.

Such a thing as kg (Force) does not exist. Only some people familiar with the Imperial system transfer that from that system as it is used there.

In the Imperial system mass is given in slug. 1 slug ~ 32 lb (force).

There was a unit 'kilopond' kp used in metric system to represent kg force. I do not know if this has been discontinued

I think the kilopond, is another unit like the pascal is when dealing with pressure or stress, generally too small, that is why in the main we use kPa and MPa. Mind you I haven't heard that term kilopond for many year.(I think it is of historical interest only).

Ah........... 1N = 0.102kp.......... and when you consider that a Newton is the force required to to give a mass of 1 kilogram an accelaration of 1m/sec² AND

1 Pascal is the force or pressure of 1 Newton applied over an area of 1m²

I'm not replying to the question as it's been answered several times already.

I just want to point out that this is a simple question and I expected no more than two or three replies to get it straightened out. I'm surprised to find this thread is already at 17 (18 counting mine) posts.

Hi!!!!

Cumic meter means Volume, Kg means Weight we can't descripe Volume to Weight. Because it will be vary on their Density.

We can calulate their self weight.

Example : 1 Cum = 1000 Litre Volume (For water )

Water Density 1000 Kg / Cum (For fresh Water)

Water Density 1105 Kg / Cum (For HeavyWater)

You have to know first density of Materials, then u can convert from Cubic metre to Kilo gram.

Thanks & Regards

Example : 1 Cum = 1000 Litre Volume (For water )

Sorry to disappoint you old chap, BUT:- 1m³ of any liquid = 1 000 litres

Right you are, Mobi.

And furthermore to the prior pal, kg is mass not weight.

Rolf

Thanks Rolf, I missed that one......................too eager I guess.

thanks for your answer i get an idea about this

You are asking for a conversion that is not possible : Kilogram is a unit of mass while cubic metres is a unit of volume.For this type of conversion,you will need the density of the product.This will be in the same units : kg/cubic metre

For water the value is 1000 ( kg/m^3)

for solids this would have higher value ; e.g. iron - 7800

Mercury : 13600 and so on.

Concersion of cubic metres to kgs will need the former to be multiplied by density:i.e

Cubic metres x density = kg

Take of the units of density !

You need to state the temperature and pressure, and you need to know the density of air at that temperature and pressure. There are references where you can look it up, or you can estimate from ideal gas law.

However, OSHA and EPA state permissible levels of dust and all particulates in g/m³, with appropriate prefix on the grams. Only gases are stated on a ppm basis and it is based on mole fraction.

Hi

1 cubic metre of building sand = How many Kgs ?
