Summary

Enter width, thickness, and length of a lead flat bar to instantly calculate its weight using the standard lead density of 11.34 g/cm³.

How it works

  1. Enter the flat bar width in millimeters (metric) or inches (imperial).
  2. Enter the flat bar thickness in millimeters or inches.
  3. Enter the total bar length in meters or feet.
  4. Select your preferred unit system using the Metric / Imperial toggle.
  5. Optionally enter a quantity to calculate the total weight for multiple bars.
  6. The calculator applies the formula: Weight = Width × Thickness × Length × 11.34 g/cm³ and returns results in kg and lb.
