Boulder Weight Calculator

The Boulder Weight Calculator is designed to help you estimate the weight of a boulder using either basic or advanced calculations.

By entering dimensions, density, or volume, you can quickly determine the approximate weight, which is useful for transportation and construction planning.

Boulder Weight Calculator

This calculator helps you determine the weight of a boulder by using its dimensions and density, or you can calculate other parameters if some are already known.

Basic Calculator:

  1. Enter any three of the following values:
    • Length (ft), Width (ft), Height (ft) of the boulder.
    • Density (lbs/ft³) to find the weight.
  2. Click Calculate to determine the missing value or Reset to clear fields.

Advanced Calculator:

  1. Enter:
    • Volume (ft³) and Density (lbs/ft³) of the boulder.
    • Shape Factor to account for different shapes (e.g., Cube, Sphere, Irregular).
  2. Click Calculate to see the adjusted weight.

Example Calculations

Example 1 (Basic Calculator):

Step Input Result
Length 4 ft  
Width 3 ft  
Height 2 ft  
Density 150 lbs/ft³  
Calculated Weight   4×3×2×150=36004 \times 3 \times 2 \times 150 = 3600 lbs

With dimensions of 4 ft x 3 ft x 2 ft and a density of 150 lbs/ft³, the boulder’s weight is 3600 lbs.

Example 2 (Advanced Calculator):

Step Input Result
Volume 30 ft³  
Density 120 lbs/ft³  
Shape Factor 0.85 (Sphere)  
Adjusted Weight   30×120×0.85=306030 \times 120 \times 0.85 = 3060 lbs

Using an estimated volume of 30 ft³, a density of 120 lbs/ft³, and a shape factor of 0.85 for a spherical shape, the calculated weight is 3060 lbs.
