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 64.24 pounds per cubic inches?
As;
1 pounds per cubic inches = 278.01378058708 kilonewton per cubic meters
64.24 pounds per cubic inches = Y kilonewton per cubic meters
Assuming Y is the answer, and by criss-cross principle;
Y equals 64.24 times 278.01378058708 over 1
(i.e.) Y = 64.24 * 278.01378058708 / 1 = 17859.605264914 kilonewton per cubic meters
Answer is: 17859.605264914 kilonewton per cubic meters are equivalent to 64.24 pounds per cubic inches.
