**Definitions:**

**Pound Per Cubic Inch** (abbreviations: **lb/in3, or ppi3**): is a unit of density, defined by mass in pound divided by volume in cubic inch

**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 Inches to Kilonewton Per Cubic Meters

*Example: How many kilonewton per cubic meters are equivalent to 12.02 pounds per cubic inches?*

As;

1 pounds per cubic inches = 278.01378058708 kilonewton per cubic meters

12.02 pounds per cubic inches = Y kilonewton per cubic meters

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

Y equals 12.02 times 278.01378058708 over 1

(i.e.) Y = 12.02 * 278.01378058708 / 1 = 3341.7256426566 kilonewton per cubic meters

Answer is: 3341.7256426566 kilonewton per cubic meters are equivalent to 12.02 pounds per cubic inches.
