Anybody know the formula to calculate the steel weight?
Volume x lbs/volume
+1 kelly
.283 lbs/cubic inch
Hello there
If you steel shape is simple their answers are right but are your shape is not as a geometric shape I suggest you model it in SolidWorks software and go to the evaluate and find its weight with a high accuracy
First calculate the volume of the steel sheet. Note: If you are calculating the weight of circular steel reinforcement bar than calculate its volume by using this formula (πD^2/4) and then just multiply by the density of steel which is 7850 kg/m^3 and you will get the final weight of the steel.
Calculate Weight of Steel Bars
1. Estimation of Steel Reinforcement for slab,beam and column.
2. Weight of steel Flat bar = (Length x width x thickness) x 7850.
3. Example 1: Determine the unit weight of MS Flat bar of width 40mm and Thickness of 20mm.
4. Weight of steel bar = Volume of steel Bar x Density of steel.

Weight is a measure of the force of gravity pulling down on an object. It depends on the object's mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object's weight in Newtons (N) and m is the object's mass in kilograms.
