**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

**Newton Per Cubic Meter** (abbreviations: **N/m3, or Npm3**): is an SI derived unit of density, defined by mass in newton divided by volume in cubic meter

## How to Convert Pounds Per Cubic Feet to Newton Per Cubic Meters

*Example: How many newton per cubic meters are equivalent to 3.69 pounds per cubic feet?*

As;

1 pounds per cubic feet = 157.08657306188 newton per cubic meters

3.69 pounds per cubic feet = Y newton per cubic meters

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

Y equals 3.69 times 157.08657306188 over 1

(i.e.) Y = 3.69 * 157.08657306188 / 1 = 579.64945459833 newton per cubic meters

Answer is: 579.64945459833 newton per cubic meters are equivalent to 3.69 pounds per cubic feet.
