소개

Rebar Weight Calculator — Total rebar weight by bar size & quantity. Enter Rebar size, Length per bar (ft), Quantity to get an instant, accurate result.

공식

Total weight = weight-per-foot × length × quantity. Weight-per-foot follows ASTM A615 standard nominal weights: #3 = 0.376 lb/ft, #4 = 0.668, #5 = 1.043, #6 = 1.502, #7 = 2.044, #8 = 2.670.

단계별 안내

  1. Enter the Rebar size.
  2. Enter the Length per bar (ft).
  3. Enter the Quantity.
  4. Click Calculate to see your result instantly.

실제 예시

Example: With Rebar size = #4, Length per bar (ft) = 10, Quantity = 5, the Rebar Weight Calculator gives Weight Per Ft Lb: 0.668, Total Weight Lb: 33.4, Total Weight Kg: 15.15.

자주 묻는 질문

Where do these rebar weights come from?
They are the standard nominal unit weights published in ASTM A615, the specification for deformed and plain carbon-steel bars used in concrete reinforcement.
Does bar grade (40, 60, 75) affect the weight?
No, weight per foot depends only on bar size/diameter — grade refers to yield strength, not mass.
What inputs does the Rebar Weight Calculator need?
You'll need to provide: Rebar size, Length per bar (ft), Quantity. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Rebar Weight Calculator?
The Rebar Weight Calculator applies the formula exactly as calculated — Total weight = weight-per-foot × length × quantity. Weight-per-foot follows ASTM A615 standard nominal weights: #3 = 0.376 lb/ft, #4 = 0.668, #5 = 1.043, #6 = 1.502, #7 = 2.044, #8 = 2.670. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Rebar Weight Calculator free to use?
Yes, the Rebar Weight Calculator is completely free, requires no signup, and runs instantly in your browser.

The Rebar Weight Calculator uses a real, verifiable formula — Total weight = weight-per-foot × length × quantity. Weight-per-foot follows ASTM A615 standard nominal weights: #3 = 0.376 lb/ft, #4 = 0.668, #5 = 1.043, #6 = 1.502, #7 = 2.044, #8 = 2.670. — so results are accurate every time, not an approximation.
