Gravel suppliers use a conversion rate of 1.75 tonnes per cubic meter of loose filled 20 mm crush but depends on the type of rock and how dry it is. Dry gravel with little or no fines has a density of 1.5 tonnes per cubic meter. When the gravel is compacted it compress by about 20%.

u will need the density. density = mass / volume so mass = volume x density
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.
AnswerThe density of gravel varies depending on many many things. For one there is packed and loose density. Next the density varies much of how many fines and coarses (sand and rock) are in the gravel mixture. There are many ways to find the density of gravel but takes a little know how. So there is no definite answer to this question.The density of compacted gravel will vary from 2100-2300 kg per cubic meter.

1.5 tonnes per Cubic metre.
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.
mass = density * volume weight = mass * acceleration due to gravity W = (2400 kg/m^3)*(1 m^3)*(9.8 m/s^2) = 23520 Newtons convert to pounds 23520 Newtons = 5287.5 lbs (note 1 lb is approximately 4.448 Newtons)

weight of ms hollow bar 20mm*20mm
20 mm = 0.020 meters 18 square meters * 0.020 meters = 0.36 cubic meters
First we need to know the density of that material. Eg the density of 20mm is 1528 kg/cum : 1528/35.28 = 43.31 kg/cft. Lets asume that wee have 500 kg 20 mm. So 20mm (kg to cft) 500/1528 = 0.327 cum(multiply by 35.28 becoz it is in cum) 0.327*35.28 = 11.53 Cu ft. So 500 kg of 20mm = 11.53 cu ft

Gravel only refers to the size of a rock, which has a range of about 2mm-65mm on its largest side. A gravel driveway, for example, could be made from either homogeneous gravel (all from the same rock type) or it could be a mixture of rock types(heterogeneous).
