**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

**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 Inches to Newton Per Cubic Meters

*Example: How many newton per cubic meters are equivalent to 10.18 pounds per cubic inches?*

As;

1 pounds per cubic inches = 278013.78058707 newton per cubic meters

10.18 pounds per cubic inches = Y newton per cubic meters

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

Y equals 10.18 times 278013.78058707 over 1

(i.e.) Y = 10.18 * 278013.78058707 / 1 = 2830180.2863764 newton per cubic meters

Answer is: 2830180.2863764 newton per cubic meters are equivalent to 10.18 pounds per cubic inches.
