**Definitions:**

**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

**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

## How to Convert Kilonewton Per Cubic Meters to Pounds Per Cubic Inches

*Example: How many pounds per cubic inches are equivalent to 73.54 kilonewton per cubic meters?*

As;

1 kilonewton per cubic meters = 0.0036839440220241 pounds per cubic inches

73.54 kilonewton per cubic meters = Y pounds per cubic inches

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

Y equals 73.54 times 0.0036839440220241 over 1

(i.e.) Y = 73.54 * 0.0036839440220241 / 1 = 0.27091724337965 pounds per cubic inches

Answer is: 0.27091724337965 pounds per cubic inches are equivalent to 73.54 kilonewton per cubic meters.
