First, you need the density of pea gravel. This depends heavily on particle size and cleanness of the gravel, but a density of 3000lb/yard3 is a realistic estimate. If you want the final answer in metric, it's useful to convert the density to 1780kg/meter3. Knowing this density, you can use it as a conversion factor. You just take the mass of your Pea gravel (for example 50kg) and multiply it by 1 meter3/1780kg to make the units cancel out.
Or if you want it easy, just take the weight of your pea gravel in kilograms and divide it by 1780 to get volume in cubic meters. This is a very rough estimate, and actual values depend on the density of the pea gravel being used. The basic idea for any conversion is that you get the density and make sure it uses cubic meters.
560 cubic feet are 15.857434092 cubic meters.
This is not a valid conversion because cubic meters is a measure of volume while grams is a measure of weight or mass.
Gravel is bought in cubic quantities, or by weight. You ask "to fill" but you only give a square measure. The volume of gravel required wil depends on the depth you wish the gravel to be. To fill 81 square metres to a depth of 5 cm would require 4.05 cubic metres of material.
1 cubic meter of grave contains 50 square meters at 20mm depth (1000mm / 20mm = 50). 2860 / 50 = 57.2 So you need 57.2 cubic meters of gravel.
You can't convert that. One is a unit of length, the other, of area. You can convert meters to centimeters, square meters to square centimeters, or cubic meters to cubic centimeters.
To convert cubic meters to weight, you need to know the density of the substance you are measuring. Multiply the volume in cubic meters by the density in kilograms per cubic meter to get the weight in kilograms. Alternatively, you can use specific gravity if the substance is a liquid.
To convert cubic meters to tonnes, you need to know the density of the material you are measuring. Multiply the volume in cubic meters by the density in tonnes per cubic meter to get the weight in tonnes. The formula is: weight (tonnes) = volume (cubic meters) * density (tonnes per cubic meter).
To convert mass (kg) to volume (cubic meters), you need to know the density of the substance. Without the density, you cannot accurately convert 400 kg to cubic meters. Density is needed to convert mass to volume.
You can convert cubic feet to cubic meters, or feet to meters. But you can't convert cubic feet to meters.
You can't convert just Kgs. to cubic metres. A kilogram is a measure of weight while a cubic meter is a measure of size.
You will need to know the weight of the plastering. If you identify a weight per cubic meter, multiply it by the number of cubic meters that you have.
It would depend on the contents of the cubic meter, 4 cubic meters of air would not have a measureable weight, and 4 cubes of sand/gravel would weigh considerably more.
To convert a thousand standard cubic feet to million cubic meters, you would first convert standard cubic feet to cubic meters by dividing by 35.3147. Then, divide the result by 1,000 to convert cubic meters to million cubic meters.
To convert cubic meters to cubic centimeters, multiply the number of cubic meters by 1,000,000 (since there are 1,000,000 cubic centimeters in a cubic meter). For example, to convert 3 cubic meters to cubic centimeters, you would calculate 3 cubic meters * 1,000,000 = 3,000,000 cubic centimeters.
Multiply cubic meters by 1,000.
To convert cubic meters to cubic millimeters, you would need to multiply the number of cubic meters by 1,000,000,000 (since there are 1,000,000 cubic millimeters in a cubic meter).
There is no direct conversion. Cubic meters is volume and square meters is area.
