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
Tonne Per Cubic Meter (abbreviations: t/m3, or tpm3): is a unit of density, defined by mass in tonnes divided by volume in cubic meter
How to Convert Pounds Per Cubic Inches to Tonnes Per Cubic Meters
Example: How many tonnes per cubic meters are equivalent to 31.09 pounds per cubic inches?
As;
1 pounds per cubic inches = 28.35 tonnes per cubic meters
31.09 pounds per cubic inches = Y tonnes per cubic meters
Assuming Y is the answer, and by criss-cross principle;
Y equals 31.09 times 28.35 over 1
(i.e.) Y = 31.09 * 28.35 / 1 = 881.4015 tonnes per cubic meters
Answer is: 881.4015 tonnes per cubic meters are equivalent to 31.09 pounds per cubic inches.
