develop a conversion factor for the Ib/in^3 to kg/m^3 ?

i need detial~~~~

Solution

lb/in^3 to kg/m^3

1lb = 0.4536 kg
1 meter =39.37 inches
So, 1 m^3 =(39.37)^3 in^3
1 m^3 = 61023.377953 in^3

lb/in^3 * (0.4536 kg / 1 lb) * ( 61023.377953 in^3 / 1 m^3)

Cancelling the lb and m^3 units :

(0.4536 * 61023.377953) kg / m^3

27680.204 kg/m^3

So, 1 Lb/in^3 = 27680.204 kg/m^3 --> required conversion factor
