**Definitions:**

**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.
