Calculating the weight of round bar

that' easy!

calculate area of cross section & multiply by length & then multiply the final value by density of that matl

wt = ((π/4) x d² x l) x ρ

where,

π = 3.14

d = diameter of bar,

l = length of bar,

ρ = density of bar material

For mild steel : ρ (density) = 7850 Kg/m³ = 490.0596 lb/ft³

Factor for steel also given as .2836 lb per in^3.

If you are looking at trying to control to tight gram weight tolerance for forging blanks, calculate for both the minimum and maximum of the diameter tolerance, as well as the minimum and maximum length tolerance of your cutting process.

You have been given correct methodolgies for calculation by prior respondents.

density and specif gravity are same

hi,

here is the answer

diameter*diameter*0.0019= the weight of round steel bar in one foot

Don't use this it isn't even close.

1" rd bar 1 foot long = 2.6376 pounds.

using this guest's formula

1 inch times 1 inch times .0019 = .0019 pounds.

OD X OD X LENGTH X .00000628

NOTE : ALL DIMENSIONS ARE IN MM.

One should not use this answer as the .00000628 factor' s units are not given, nor is the factor identified as to what material it might be valid. It has been my exerience that once Mssr Abdul Halim Galala has posted, There is really not much to add. milo

how to calculate the length

Dear,

This is THE Best answer of calculating weight of Mild Steel using Length and Dia

Regards

rajendra

thanks how to calculate of hex bar

And the guest never came back to inform the most basic data: what is the material ? It may be plastic as well (or Teflon - we buy regularly)

Mild steel 700 mm dia per mtr weight ?

Mild steel 800 mm dia per mtr weight ?

Mild steel 700 mm dia per mtr weight = 0.7 x Mild steel Φ1m x 1m

Mild steel 800 mm dia per mtr weight = 0.8 x Mild steel Φ1m x 1m

never learnt math in your college?
