A Bolt Weight Calculator is a tool designed to help you calculate the weight of a bolt. This is useful in various fields such as construction, manufacturing, and engineering, where knowing the exact weight of components is crucial. By inputting the diameter, length, and density of the bolt material, the calculator provides an accurate weight measurement.

## Purpose and Functionality

The primary purpose of a Bolt Weight Calculator is to simplify the process of determining the weight of bolts. Instead of manually performing complex calculations, this tool quickly and accurately provides the weight by following a specific formula. This is especially useful for professionals who need to ensure the correct weight of bolts for their projects.

## Formula for Bolt Weight Calculation

The weight of a bolt can be calculated using the following formula:

Weight=Volume×Density\text{Weight} = \text{Volume} \times \text{Density}Weight=Volume×Density

### Inputs

**Diameter (D)**: Diameter of the bolt in millimeters (mm)**Length (L)**: Length of the bolt in millimeters (mm)**Density (ρ)**: Density of the material in grams per cubic centimeter (g/cm³)

### Calculations

**Calculate the Radius (r)**: r=D2r = \frac{D}{2}r=2D**Convert Radius to centimeters (cm)**: rcm=r10r_{cm} = \frac{r}{10}rcm=10r**Convert Length to centimeters (cm)**: Lcm=L10L_{cm} = \frac{L}{10}Lcm=10L**Calculate the Volume (V) of the bolt (assuming a cylindrical shape)**: V=π×rcm2×LcmV = \pi \times r_{cm}^2 \times L_{cm}V=π×rcm2×Lcm**Calculate the Weight (W)**: W=V×ρW = V \times \rhoW=V×ρ

## Example Calculation

Let's calculate the weight of a steel bolt with the following specifications:

- Diameter (D) = 12 mm
- Length (L) = 100 mm
- Density (ρ) = 7.85 g/cm³

### Step-by-Step Calculation

**Calculate the Radius (r)**: r=122=6 mmr = \frac{12}{2} = 6 \text{ mm}r=212=6 mm**Convert Radius to centimeters (cm)**: rcm=610=0.6 cmr_{cm} = \frac{6}{10} = 0.6 \text{ cm}rcm=106=0.6 cm**Convert Length to centimeters (cm)**: Lcm=10010=10 cmL_{cm} = \frac{100}{10} = 10 \text{ cm}Lcm=10100=10 cm**Calculate the Volume (V)**: V=π×(0.6)2×10V = \pi \times (0.6)^2 \times 10V=π×(0.6)2×10 V=3.14×0.36×10V = 3.14 \times 0.36 \times 10V=3.14×0.36×10 V=11.304 cm3V = 11.304 \text{ cm}^3V=11.304 cm3**Calculate the Weight (W)**: W=11.304×7.85W = 11.304 \times 7.85W=11.304×7.85 W=88.73 gW = 88.73 \text{ g}W=88.73 g

So, the weight of the bolt is approximately 88.73 grams.
