How do you calculate rebar for concrete?

Answer

There are concrete rebar calculations available on the Internet as well as through some concrete dealers. Concrete and rebar can be purchased from home improvement stores like Lowe's and Home Depot. When attempting to calculate how much rebar is needed for the concrete reinforcing, one needs to know the entire length and width of the structure, along with the spacing the bars will be in. In a typical calculator, after filling in such things as edge clearance and bar size, you should be able to get the number of rebar needed.

1 Additional Answer
In a construction project, the rebar needs to be calculated so you know what to bill the customer for labor and materials. The number is important because your estimate depends on this number, and is found using a simple formula. Begin your calculations by subtracting 0.5 from the length of the slab. Multiply that by the number of bars that will be used in the project. Multiply that number by the weight of the bar. Repeat the process with the width of the slab, then add both sums together to obtain the total rebar for that slab of concrete.
