There can be no conversion.
A kilogram is a measure of mass. A cubic metre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
Kilogram per cubic meter is the one that doesn't belong. Square meter is meter^2 and cubic meter is meter^3 but kilogram per cubic meter is a density
849 klgms of granulated sugar = 1 cubic meter
These are all easy to find in your book: Length . . . . . . . Meter Mass . . . . . . . . . Kilogram Volume . . . . . . . Cubic Meter (* Liter is 1/1000th m3, or one dm3) Density . . . . . . . Kilogram per cubic meter Time .. . . . . . . . . Second Temperature . . . Kelvin or Celsius degree (same size)
If it was a cubic meter of water then its mass would be 1000 kg or 1 metric ton.
Mass: kilogram, length: meter, volume: cubic meter, density: kilogram / cubic meter, temperature: celcius or kelvin.
A cubic meter is one thousand liters. It is designed to relate to the weight of water, so one liter weighs one kilogram. A cubic meter of water weighs one thousand kilos, or one metric ton.
The medium density should given to convert from mass (kilogram) to volume (1 cubic meters). Assuming water of 1000 kg/cubic meter, than 1 cubic meter would contain 1000 kilograms,
Mass: the kilogram. Density: kilogram per cubic meter.
Kilogram/liter, or kilogram/cubic meter.
compare 0.76 cubic meter to kilogram
Mass: kilogram Length: meter Volume: cubic meter
It depends on the density of the cement. You wont get an accurate answer without the details.
