you cant unless you know the density
400kg/m3
cubic centimetres / 1,000,000 = cubic metres
2.747 m3
convert 40 cm3 to m3
To convert from cubic meters (m3) to liters (L), you multiply the volume in cubic meters by 1000. This is because 1 cubic meter is equal to 1000 liters. So, the conversion formula is: volume in liters = volume in cubic meters x 1000.
You cannot convert m2 to m3 without a third measurement as a cubic measurement is width plus length pus depth.
1.00 Ccf equals 2.8317 m3
1mm BTU= 28.26 m3
Pounds per cubic foot x 16.0184634 = kg/m3
1 gram = 0.001 kilogram 1 centimetre =0.01 metre so that 1 cm3 = 0.000001 m3 Therefore, 1 gram per cm3 = 0.001 kg per 0.000001 m3 = 1000 kg/m3. So to convert from gram per cubic centimetre to kilogram per cubic metre, multiply by 1000.
6 litres in m3. a litre is 1000cm3. so divide that by 103 to convert to m3. That is 0.000001m3. 6 litres is 0.000006m3
818,000 cubic meters = 216,100,000 US gallons. (m3 x 264.2 = US gallons)
