Green Log Weight Calculator

Introduction: Whether you’re a logger, a lumberjack, or simply someone interested in the forestry industry, knowing the weight of green logs can be essential for various purposes. Green logs, or freshly cut logs, have a specific weight that can influence transportation, processing, and pricing. The Green Log Weight Calculator is a practical tool for estimating the weight of green logs based on their length and diameter.

Formula: The Green Log Weight Calculator employs a straightforward formula to calculate the weight of green logs:

Green Log Weight = π * (Log Diameter / 24)^2 * Log Length * 62.4

This formula accounts for the log’s diameter in inches, its length in feet, and a standard wood density of 62.4 pounds per cubic foot.

How to Use: Using the Green Log Weight Calculator is easy. Input the log’s length in feet and its diameter in inches. After providing these values, click the “Calculate” button. The calculator will display the estimated weight of the green log in pounds.

Example: Let’s consider a practical example:

  • Log Length: 10 feet
  • Log Diameter: 18 inches

Upon clicking “Calculate,” the calculator will display a green log weight of approximately 415.92 lbs.


  1. Why is it important to know the weight of green logs?
    • The weight of green logs is crucial for transportation, processing, and pricing in the forestry industry.
  2. Can this calculator be used for different types of wood, or is it specific to a particular wood species?
    • This calculator provides a general estimation and can be used for various wood types.
  3. What is the significance of using a log’s green weight as opposed to its dry weight?
    • Green weight accounts for the log’s weight immediately after cutting, while dry weight factors in moisture loss over time.
  4. How does the diameter of a log affect its weight?
    • The larger the diameter, the heavier the log, as weight increases with the cross-sectional area.
  5. Is the density of 62.4 pounds per cubic foot a standard value for all types of wood?
    • No, wood density can vary by species, but 62.4 pounds per cubic foot is commonly used as a rough average.
  6. Can I use this calculator for logs of various lengths and diameters?
    • Yes, the calculator is versatile and can be used for logs of different sizes.
  7. How does knowing the weight of green logs impact the lumber industry?
    • It helps determine transportation costs, processing requirements, and pricing for lumber.
  8. Can I use this calculator for non-cylindrical logs, such as irregularly shaped logs?
    • The calculator is designed for cylindrical logs, but it can provide rough estimates for irregularly shaped logs.
  9. Is it necessary to account for moisture content when calculating green log weight?
    • This calculator assumes a green log with standard moisture content.
  10. What other parameters are important when dealing with green logs in the forestry industry?
    • Factors like log grade, species, and local market conditions are also significant considerations.

Conclusion: The Green Log Weight Calculator is a handy tool for individuals involved in the forestry and lumber industries, as well as anyone interested in understanding the weight of freshly cut logs. Knowing the weight of green logs can impact various aspects of the industry, from transportation and processing to pricing and logistics. While this calculator provides a general estimation, it can be a useful resource for initial calculations and planning. Keep in mind that specific wood species and variations in moisture content can affect the precise weight, making professional evaluation essential for precise applications.
