In this article we provide weight of #2, #3, #4, #5, #6, #7, #8, #9 and #10 US/ imperial rebar, US based steel/ reinforcing bar sizes and their diameter, as we know that different countries in the world have their own gradation, specification of Steel and record of measurement for reinforcing bar, we briefly explain the different imperial bar sizes, their nominal diameter in inches and millimetre, their nominal area in square inches and Square millimetre and their mass per unit length in pound per foot and kg per metre. This will help to viewers in better understanding and it is easy to choose the most suitable rebar you wanted according to requirement.

Rebar is short form of reinforcing bar, it is steel bar or Steel wire provided as tension bar, used in reinforced concrete structure like column, beam and slab of house construction and it also used in reinforced masonry structure. It is used to increase the strength of concrete structure.

Reinforcing bar/rebar surface is often deformed with ribs to promote a better bonding with concrete material and reduce the risk of slippage. The most common Reinforcing bar/rebar is carbon steel of hot rolled round bar with the deformation patterns, the Steel rebar may be also coated with epoxy resin material, design to resist effect of corrosion mostly in saltwater environment.

Why rebar is provided in concrete structure? The concrete material is good in compression but relatively weaker in tention, to compensate for this in balance in concrete behaviour, reinforcing bar/ rebar embeded into it to carry tensile load.

US/ imperial rebar sizes gives the diameter in units of 1/8 inch (3.2mm), for bar sizes #2 to #10 we use the formula, size of rebar = number of bar × 1/8 inch.

US/ Imperial steel rebar/ reinforcing bar available in different size like #2 (read as number 2 rebar or No. 2), #3 (read as number 3 rebar or No 3), #4 (read as number 4 rebar or No 4), #5 (read as number 5 rebar or No 5), #6 (read as number 6 rebar or No 6), #7 (read as number 7 rebar or No 7), #8 (read as number 8 rebar or No 8), #9 (read as number 9 rebar or No 9), #10 (read as number 10 rebar or No 10), #11 (read as number 11 rebar or No 11), #14 (read as number 14 rebar or No 14) and #18 (read as number 18 rebar or No 18). It will be also customise according to requirement of customers.

**Weight of #2, #3, #4, #5, #6, #7, #8, #9 and #10 US/ imperial rebar**

To find weight of Steel bar per metre we have to follow some essential rules and steps, first we should select unit measured in metre or feet, then select shape of bar, it is round bar then select bar size, select length in metre and find Unit Weight of steel is calculated.

There is a formula to be derived is d^2/162, where d is size/ diameter of rebar/ reinforcing bar, zooming cross-section is circular and material is cylinder and unit weight/density of steel rebar is about 7850kg/m3. d^2/162, this formula will help to find out weight of different size #2, #3, #4, #5, #6, #7, #8, #9 and #10 US/ imperial rebar.
