Log Weight Calculator
When working with timber, whether for construction, crafting, or firewood, knowing the weight of logs is crucial. Why? Because the weight affects transportation, handling, and structural integrity. A Log Weight Calculator helps you determine how much a log weighs based on its dimensions and type, enabling you to make informed decisions for your projects.
How Does the Log Weight Calculator Work?
To calculate the weight of a log, you need to know:
- Diameter (in inches or centimetres)
- Length (in feet or meters)
- Wood Density (varies by species, often measured in kg/m³ or lb/ft³)
The formula for calculating the weight of a log is:
Weight (kg) = Length (m) × Diameter² (m²) × Wood Density (kg/m³) × π/4
Example Calculation
Let’s say you have a log that is:
- Diameter: 30 cm (0.3 m)
- Length: 2 m
- Wood Density: 600 kg/m³ (typical for many hardwoods)
- Convert Diameter:
Diameter=30 cm=0.3 m
- Calculate the Weight:
Weight=2m×(0.3m)2×600kg/m3×4π
Weight=2×0.09×600×0.7854≈85.0kg
Real-Life Applications
Understanding the weight of logs is crucial for various projects. Below is a table that outlines different scenarios where a Log Weight Calculator can be utilised, including calculations for each application:
| Project | Diameter | Length | Wood Density (kg/m³) | Weight (kg) |
| Building a Wooden Shed | 20 | 3 | 500 | Weight = 3 × (0.2)² × 500 × (π/4) = 31.4 kg |
| Creating Furniture | 15 | 1.5 | 600 | Weight = 1.5 × (0.15)² × 600 × (π/4) = 18.0 kg |
| Chopping Firewood | 30 | 1 | 700 | Weight = 1 × (0.3)² × 700 × (π/4) = 49.5 kg |
| Crafting Wood Sculptures | 10 | 0.5 | 450 | Weight = 0.5 × (0.1)² × 450 × (π/4) = 3.54 kg |
Using a Log Weight Calculator can save you from miscalculations. Input the correct numbers and get the right calculation every time. Try it now.
