Planning weight for the most common stainless grade
304 is widely used in food equipment, architectural hardware, tanks, general chemical service, and shop-built components. Bar weight affects handling and freight long before corrosion resistance or finish becomes the dominant design question.
Cold work can change mechanical properties, but nominal weight still follows section volume and alloy density. Include extra cut or machining stock in the dimensions when the purchased blank is larger than the finished part.
Weight formulas used by this calculator
Round bar and solid rod
weight = pi x (diameter / 2)^2 x length x density
Diameter is the full outside dimension of solid bar. Tube and bored stock need the hollow internal volume subtracted.

Frequently asked questions
What density does the 304 bar calculator use?
It uses 0.289 lb/in3, equivalent to about 8.00 g/cm3.
How much does one-inch 304 round bar weigh per foot?
One-inch-diameter 304 round bar weighs about 2.72 pounds per foot.
Is 304 stainless heavier than carbon steel?
It is usually slightly heavier by volume. 304 is about 0.289 lb/in3, while common carbon-steel estimates often use roughly 0.284 lb/in3.
Does annealed 304 need a different density?
No separate practical factor is needed for an annealed bar weight estimate.
