Size to Weight Calculator
Calculate weight from dimensions and material density for rectangular objects
Calculate Object Weight
Select material to automatically set density, or choose custom
Object Dimensions
Length of the rectangular object
Width of the rectangular object
Height/thickness of the rectangular object
Density of the material (mass per unit volume)
Weight & Volume Results
Formula: Weight = Volume × Density
Volume: 0.000 × 0.000 × 0.000 = 0.000000 m³
Material: Custom Material (0 kg/m³)
Weight Analysis
Practical Examples
Standard Brick Weight
Dimensions: 92 × 57 × 203 mm
Material: Brick (2,000 kg/m³)
Volume: 0.092 × 0.057 × 0.203 = 0.001066 m³
Weight: 0.001066 m³ × 2,000 kg/m³ = 2.13 kg
Steel Beam Section
Dimensions: 100 × 50 × 1000 mm
Material: Steel (7,850 kg/m³)
Volume: 0.1 × 0.05 × 1.0 = 0.005 m³
Weight: 0.005 m³ × 7,850 kg/m³ = 39.25 kg
Wooden Block
Dimensions: 10 × 10 × 5 cm
Material: Oak Wood (750 kg/m³)
Volume: 0.1 × 0.1 × 0.05 = 0.0005 m³
Weight: 0.0005 m³ × 750 kg/m³ = 0.375 kg
Common Material Densities
Unit Conversions
Length:
1 m = 100 cm = 1000 mm
1 ft = 12 in = 0.3048 m
Volume:
1 m³ = 1,000,000 cm³
1 m³ = 35.31 ft³
Weight:
1 kg = 1000 g = 2.205 lb
1 lb = 16 oz = 0.4536 kg
Calculation Tips
Measure all dimensions in the same unit system
For hollow objects, calculate outer minus inner volume
Use material-specific density for accurate results
Consider safety factors for lifting and transport
Understanding Size to Weight Calculations
What is Size to Weight Calculation?
Size to weight calculation determines the mass of an object based on its physical dimensions and the density of its material. This is essential for construction planning, shipping calculations, structural engineering, and material handling.
Core Formula
Weight = Volume × Density
Volume = Length × Width × Height
Where density is the mass per unit volume of the material, typically measured in kg/m³.
Applications
- •Construction material weight estimation
- •Shipping and freight calculations
- •Structural load analysis
- •Equipment capacity planning
- •Material handling safety
Important Notes
Accuracy Considerations:
• Use precise material densities
• Account for material variations
• Consider hollow sections if applicable
Safety Warning:
Always verify calculations before lifting or moving heavy objects
