## Round Steel Bar Weight Formula

The formula commonly used to calculate the weight of a round steel bar is based on its diameter (D) and length (L). Here’s the formula:

Weight=Volume×DensityWeight=Volume×Density

Where:

- Volume =
*π*×(2/*D*)^{2}×*L*(Volume of a cylinder) - Density = Density of steel (typically around 7.85 g/cm
^{³}or 7850 kg/m^{³})

So, the formula for the weight of a round steel bar can be expressed as:

Weight= *π*×(2/*D*)^{2}×*L*×Density

Or, if you prefer:

Weight==(*π*×*D*^{2}×*L*×Density)/4

This formula calculates the weight in kilograms. Make sure to use consistent units for diameter (typically in millimeters) and length (typically in meters) to get accurate results.
