you cannot, they are two different types of measurements. if you have the density of the substance you have the weight for. you could divide the weight/density.
62.4 pounds per feet cubed converts to about 1000kg per meter cubed.
Here's how I do it. You may find another procedure that you like better.-- take the number of meters cubed-- multiply it by 35.3147-- the answer is feet cubed in the same area
2.3 cubic feet = 3,974.4 cubic inches

The density of aluminum is approximately 0.098 pounds per cubic inch. To convert this to pounds per cubic foot, you would first convert cubic inches to cubic feet (1 cubic foot = 1728 cubic inches) and then multiply by the density in pounds per cubic inch. Therefore, the density of aluminum in pounds per cubic foot is approximately 169 pounds per cubic foot.
40 pounds per cubic foot equates to 640.74 kg per cubic meter.
You can't convert that - it just doesn't make sense.
Mass can be measured in pounds in the nearly obsolete Imperial system. You can measure the legth of various items in feet but you cannot convert length to feet.
Lbs (pounds) are a unit of weight. Ft (feet) are a unit of length. There is no way to universally convert between the two and make any sense at all.
Inches cubed x 16.387 = cm cubed

There are 35.315 cubic feet in a meter cubed.... .....and I am not anonymouse or a vandal or a visgoth....!!!!!!!
