For imperial weight calculations certain measurements (fractions) need to be converted to decimal inches.

 

For an accurate calculation it is also important to allow for the rolled/drawn tolerances on diameter defined by the manufacturing specification please contact us for details.

 

Density of steel

 

The acknowledged density of mild steel is 7.85 g/cm3(0.284 lbs/in3). Dependent on the alloy elements added to manufactured specifications this can vary between 7.75 and 8.05 g/cm3 (0.280 and 0.291 lbs/in3).
