How to calculate the weight
The weight is easily calculated. Simply multiply the appropriate alloy density by the length, width, and thickness of the required part (see worked example below).

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 rolling tolerance which affects the thickness and the cutting tolerances which affect the width and length. These vary from thickness to thickness – please contact us for details.
Density of steel
The acknowledged density of mild steel is 7.85 g/cm3 (0.284 lbs/in3). Depending 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).
