It is impossible to convert cubic area (volume) into mass without any further information but if you have the mass and the cubic area (volume), you can multiply them by each other (eg: v*a), you can work out the density. If you're interested in this subject, you could always look into it.
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
That's the same as converting cubic meter to kilograms. You can't do it, unless you know the density of the specific substance you are working with.
Mass: kilogram, length: meter, volume: cubic meter, density: kilogram / cubic meter, temperature: celcius or kelvin.
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)
convert 40 cm3 to m3
849 klgms of granulated sugar = 1 cubic meter
Assuming that a kilo refers to a kilogram, you don't. A kilogram is a measure of mass. A cubic metre is a measure of volume. The two measure different things and it is not sensible to even consider converting from one to the other. If you are not convinced, consider a cubic metre of air. How many kilograms? Next consider a cubic metre of lead. How many kilograms?
Mass: the kilogram. Density: kilogram per cubic meter.
Kilogram/liter, or kilogram/cubic meter.
If it was a cubic meter of water then its mass would be 1000 kg or 1 metric ton.
