The weight of rebar calculator is a tool used to calculate the weight of steel reinforcement bars, commonly known as rebar, based on their diameter, length, and quantity. This calculator is used in construction projects to determine the weight of rebar required for a particular job, which helps in estimating the total cost of the project accurately.

The formula used in the weight of rebar calculator is

W = (D^2/162.28) * L

where W is the total weight of the rebar in kilograms

D is the diameter of the rebar in millimeters

and L is the length of the rebar in meters.

This formula is based on the weight per unit length of rebar, which is 0.00617 kg/m^2 for a diameter of 1 millimeter.

For example, if you have 10 rebar rods with a diameter of 16 millimeters and a length of 6 meters, the weight of each rod can be calculated as follows:

W = (16^2/162.28) * 6 W = 9.88 kg

Therefore, the total weight of the 10 rods would be:

Total weight = 10 * 9.88 = 98.8 kg

Here are some FAQs about the weight of rebar calculator:

1. How do I use the weight of rebar calculator?

To use the weight of rebar calculator, enter the diameter, length, and quantity of rebar rods in the input fields, select the unit of measurement, and click on the “Calculate” button. The calculator will then display the total weight of the rebar and the weight per meter or feet.

1. What is the weight per meter or feet of rebar?

The weight per meter or feet of rebar depends on the diameter of the rebar and the unit of measurement. For example, if the diameter of the rebar is 12 millimeters, the weight per meter would be 0.888 kg/m, and the weight per feet would be 0.2709 kg/ft.

1. How can I estimate the quantity of rebar required for a project?

To estimate the quantity of rebar required for a project, you need to know the area of concrete that needs to be reinforced and the spacing between the rebar rods. Once you have this information, you can calculate the required number of rebar rods using the formula: number of rods = (area of concrete x spacing between rods) / (diameter of rebar x length of one rod). You can then use the weight of rebar calculator to determine the total weight of rebar required.
