How to Convert Pounds Per Cubic Feet to Kilonewton Per Cubic Meters

Example: How many kilonewton per cubic meters are equivalent to 81.7 pounds per cubic feet?


As;

1 pounds per cubic feet = 0.15708657306188 kilonewton per cubic meters

81.7 pounds per cubic feet = Y kilonewton per cubic meters

Assuming Y is the answer, and by criss-cross principle;

Y equals 81.7 times 0.15708657306188 over 1

(i.e.) Y = 81.7 * 0.15708657306188 / 1 = 12.833973019155 kilonewton per cubic meters

Answer is: 12.833973019155 kilonewton per cubic meters are equivalent to 81.7 pounds per cubic feet.
