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
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
How to Convert Pounds Per Cubic Feet to Kilonewton Per Cubic Meters
Example: How many kilonewton per cubic meters are equivalent to 72.5 pounds per cubic feet?
As;
1 pounds per cubic feet = 0.15708657306188 kilonewton per cubic meters
72.5 pounds per cubic feet = Y kilonewton per cubic meters
Assuming Y is the answer, and by criss-cross principle;
Y equals 72.5 times 0.15708657306188 over 1
(i.e.) Y = 72.5 * 0.15708657306188 / 1 = 11.388776546986 kilonewton per cubic meters
Answer is: 11.388776546986 kilonewton per cubic meters are equivalent to 72.5 pounds per cubic feet.
