How to use Steel Plate Mass Calculator:

User Input Section:

  • Length (cm):, Width (cm):, and Thickness (cm): are input fields provided to the user.
  • Users need to input the dimensions of the steel plate they want to calculate the mass for. All fields are required.

Submit Button:

  • The user clicks on the “Calculate Mass” button after entering the dimensions.

Volume Calculation:

  • The calculator calculates the volume of the steel plate in cubic centimeters (cm³) using the formula:mathematicaCopy codeVolume = Length × Width × Thickness

Mass Calculation:

  • The mass of the steel plate is calculated in grams (g) based on the known density of steel. The density of steel is assumed to be 7.8 grams per cubic centimeter (g/cm³). The formula for mass is Mass = Volume × Density

Result Display:

  • The calculated mass is displayed to the user in the “result” paragraph. It shows the approximate mass of the steel plate in grams.

Formula Used

Volume Calculation Formula:

  • Volume = Length (cm) × Width (cm) × Thickness (cm)

Mass Calculation Formula:

  • Mass = Volume (cm³) × Density (g/cm³)


  • Length (cm) is the length of the steel plate.
  • Width (cm) is the width of the steel plate.
  • Thickness (cm) is the thickness of the steel plate.
  • Density (g/cm³) is the density of steel, which is assumed to be 7.8 g/cm³ in this calculator.

The calculator takes user input for the dimensions, calculates the volume of the steel plate, and then uses the volume and steel density to determine the mass. The result is displayed to the user after the calculation is completed.

This calculator provides a simple way to estimate the mass of a steel plate based on its dimensions and a standard density value for steel.
