There is no way to answer the question if you do not specify the material. Why? Because a cubic meter (or cubic foot, or gallon, or liter, or pint) of crushed stone will weigh more than a cubic meter of Styrofoam. Put another way, a ton of gravel will occupy far less space than a ton of Styrofoam. Crushed stone, for example, has a density of 100 pounds per cubic foot (lb/ft3), which is 1600 kilograms per cubic meter (kg/m3), which is 1.6 metric tons per cubic meter. Packed earth is about 95 lb/ft3, or 1520 kg/m3. If you wish to convert to US tons per cubic meter, use Google. Just type "100 pounds per cubic foot in tons per cubic meter" in the search bar. See the nearby link for densities of common building materials.
You need to know the density of the material concerned
you can't unless you know the density of the material. EG. water has density 1000 kg/m3
so 1 ton water = 103 kg = 1 m3.
How to convert cubic meters to tons of armour rock with 2.7 specific
To convert 2.66 tons per cubic meter to tons per cubic feet, you first need to convert cubic meters to cubic feet. There are approximately 35.3147 cubic feet in 1 cubic meter. Once you have the conversion factor, multiply the given value (2.66 tons per cubic meter) by the conversion factor to get the equivalent value in tons per cubic feet.
2.7 t
The conversion from cubic meters to tons depends on the density of the material you are measuring. Without that information, it's not possible to convert directly from cubic meters to tons.
To convert cubic meters to tons, you need to know the density of the substance you are measuring. The conversion factor depends on the material being measured. Once you have the density, you can use the formula: weight (in tons) = volume (in cubic meters) x density (in tons per cubic meter).
You can convert cubic feet to cubic meters, or feet to meters. But you can't convert cubic feet to meters.
There is no such thing as a "cubic ton". You can have cubic meters, but not cubic tons.
You cannot do so directly unless you know the density of the substance in question.
To convert cubic meters to metric tonnes of fuel oil, divide the volume in cubic meters by the density of the fuel oil in tonnes/m³ (or in kg/l). The density will depends upon the temperature of the fuel oil.
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.
To convert 509 tons of asphalt concrete binder course to cubic meters, you need to know the density of the material. The density of asphalt concrete binder course can vary, but a common value is around 2.2 tons per cubic meter. Using this value, 509 tons would be approximately 231.36 cubic meters.
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.
