Need help in figuring out your material consumables? The Rebar Calculator contains equations and data specifically used in working with reinforcement bars (rebar) in concrete slabs… and much more.

#### What is vCalc?

vCalc has hundreds of calculators and thousands of equations created by engineers, university professors, students from around the world, and people like you. Topics range from complex scientific equations to practical everyday equations. Learn More

## Types of Calculators

- Rebar Diameter: Provides the diameter of different sizes of rebar.
- Length of Rebar in a Grid: Computes the linear feet of rebar in one or more mats of rebar.
- Weight of Rebar in a Grid: Computes the weight of rebar in one or more mats of rebar.
- Weight of a Length of Rebar: Computes weight from a rebar size and any length.
- Area of a Concrete Slab: Computes the area based on length and width of a rectangular slab.
- Volume of a Concrete Slab: Compute the cubic yards of concrete needed for a slab.
- Weight of a Concrete Slab: Computes the approximate weight of concrete in a slab.
- Weight of Rebar Grid and Concrete Slab: Computes the combined slab and rebar weight.
- Rebar – Irregular Shaped Slab: Estimates the amount of rebar in an irregular shaped slab.
- Volume of a Circular Slab: Computes the cubic yards of concrete in a circular slab.
- Rebar in a Circular Slab: Computes the length and weight of rebar in a circular slab.
- Concrete Displaced by Rebar: Computes the cubic yards displaced by rebar in a slab.
- Wall – Rebar, Concrete and Forms: Computes the amount of rebar, concrete and material for forms needed for a concrete wall.
- Rebar Lapping Length: Computes the length overlap needed at rebar joints based on the size of the rebar.
- Cost of Rebar: Provides the cost of rebar on a project.
- The Rebar Calculator also has concrete functions to help you compute:
- Surface Areas of slabs in square feet, yards and meters
- Volume of Concrete in slabs in cubic yards and meters
- Amount of plywood or OSB needed for wood forms for poured concrete walls

#### Rebar Calc in Spanish

The Rebar Calculator is now available in Spanish. It has Spanish language descriptions, labels and diagrams and it also has default units in the metric system (SI). The lengths are in meters and centimeters, the areas are in square meters, the volumes are in cubic meters, and the weights are in kilograms and metric tons.
