Rebar Weight Calculator

Formula

The formula to calculate the Rebar Weight is:

$RW = \pi \left( \frac{r}{12} \right)^2 \cdot L \cdot 490$

Where:

$RW$ is the Rebar Weight in pounds (lbs)
$r$ is the rebar radius in inches
$L$ is the rebar length in feet

What is Rebar Weight?

Rebar Weight refers to the weight of a steel reinforcing bar used in construction. The weight is calculated based on the radius and length of the rebar, along with a constant that represents the density of steel.

Example Calculations

Example 1:

Rebar Radius (r) = 0.5 inches
Rebar Length (L) = 10 feet

Using the formula:

$RW = \pi \left( \frac{0.5}{12} \right)^2 \cdot 10 \cdot 490 \approx 26.73 \, \text{lbs}$

The Rebar Weight is approximately 26.73 lbs.

Example 2:

Rebar Radius (r) = 0.75 inches
Rebar Length (L) = 20 feet

Using the formula:

$RW = \pi \left( \frac{0.75}{12} \right)^2 \cdot 20 \cdot 490 \approx 120.26 \, \text{lbs}$

The Rebar Weight is approximately 120.26 lbs.
