Kilonewton Per Cubic Meter (abbreviations: kN/m3, or kNpm3): is an SI derived unit of density, defined by mass in kilonewton divided by volume in cubic meter
Pound Per Cubic Foot (abbreviations: lb/ft3, or ppf3): is a unit of density, defined by mass in pound divided by volume in cubic foot
How to Convert Kilonewton Per Cubic Meters to Pounds Per Cubic Feet
Example: How many pounds per cubic feet are equivalent to 7.8 kilonewton per cubic meters?
As;
1 kilonewton per cubic meters = 6.4231142857143 pounds per cubic feet
7.8 kilonewton per cubic meters = Y pounds per cubic feet
Assuming Y is the answer, and by criss-cross principle;
Y equals 7.8 times 6.4231142857143 over 1
(i.e.) Y = 7.8 * 6.4231142857143 / 1 = 50.100291428571 pounds per cubic feet
Answer is: 50.100291428571 pounds per cubic feet are equivalent to 7.8 kilonewton per cubic meters.
