When it comes to forestry, timber, and logging, accurately calculating the weight of a green log is crucial for estimating transportation costs, pricing, and understanding the potential yield of a tree. The weight of green logs can vary depending on their size and moisture content, which is why having a reliable Green Log Weight Calculator is essential. This tool allows loggers, foresters, and others in the industry to quickly calculate the weight of a log based on its radius and length.
In this article, we will discuss how to use the Green Log Weight Calculator, the underlying formula behind the calculation, provide an example for better understanding, and answer frequently asked questions related to this tool.
What is Green Log Weight?
Green log weight refers to the weight of a freshly cut log, with its moisture content still intact. Logs can weigh significantly more when green due to the water content compared to when they are dried (kiln-dried or air-dried). Understanding the weight of a green log is important for forestry professionals to manage log transportation, pricing, and stock management.
The weight of a green log depends on its dimensions, primarily the radius and length of the log, as well as the species of wood. For this calculator, we will focus on a simplified calculation method based on two parameters: the radius and length of the log.
The formula used to calculate the weight of a green log is:
Green Log Weight = π × (log radius)² × log length × 85
Where:
- π (Pi) is a constant (approximately 3.14159).
- Log radius is the radius of the log in feet.
- Log length is the length of the log in feet.
- 85 is a constant that accounts for the typical density of green wood in pounds per cubic foot.
This formula will give the weight in pounds (lbs).
How to Use the Green Log Weight Calculator
The Green Log Weight Calculator is an easy-to-use tool that calculates the weight of a green log based on two simple inputs: the log radius and the log length. Here’s a step-by-step guide on how to use the calculator:
Step 1: Enter the Log Radius
- The log radius refers to the distance from the center of the log to its edge, measured in feet. This radius is squared as part of the formula to account for the full cross-sectional area of the log.
- Enter the log radius in the input field labeled “Log Radius (ft)”.
Step 2: Enter the Log Length
- The log length is the total length of the log, measured in feet. The longer the log, the heavier it will be.
- Enter the log length in the input field labeled “Log Length (ft)”.
Step 3: Calculate the Green Log Weight
- Once both the log radius and log length are entered, click the “Calculate” button to get the result.
- The calculator will then display the green log weight in pounds (lbs), based on the input data.
Example Calculation
To better understand how this calculator works, let’s go through an example.
Example Scenario
Imagine a log with the following characteristics:
- Log Radius: 2 feet
- Log Length: 10 feet
Now, let’s apply the formula:
Green Log Weight = π × (log radius)² × log length × 85
Green Log Weight = 3.14159 × (2)² × 10 × 85
Green Log Weight = 3.14159 × 4 × 10 × 85
Green Log Weight = 3.14159 × 340
Green Log Weight ≈ 1,068.38 lbs
So, the green log weight in this example is approximately 1,068.38 pounds.
Step-by-Step Guide to Using the Tool:
- Open the Green Log Weight Calculator on your website.
- In the first field labeled “Log Radius (ft)”, enter the radius of your log. For example, 2 feet.
- In the second field labeled “Log Length (ft)”, enter the length of your log. For example, 10 feet.
- Click the “Calculate” button.
- The weight of the green log, based on your inputs, will be displayed under the “Green Log Weight” label.

3. What units are used in the Green Log Weight Calculator?
The inputs for the calculator are in feet (for radius and length), and the result is given in pounds (lbs).
4. Why is the constant 85 used in the formula?
The constant 85 is an empirical factor that approximates the density of green wood, which can vary by species but is typically close to 85 pounds per cubic foot.
5. Can I use this calculator for logs of any type of wood?
Yes, this calculator provides an estimate of weight for green logs of any wood type, though wood species can affect the actual weight due to differences in density.
6. What is the difference between green log weight and dried log weight?
Green log weight includes the moisture content of the wood, making the log heavier than dried logs, which lose much of their water content during the drying process.
7. How accurate is the Green Log Weight Calculator?
The calculator provides a reliable estimate based on standard industry formulas, but actual log weight can vary due to factors like wood species and moisture content.
8. Can I calculate the weight of logs with different species using this calculator?
Yes, you can use the calculator for logs of different species, but be aware that the actual weight may vary based on the density of the specific wood type.
9. How does the log radius affect the weight?
The radius of the log is squared in the formula, so a small increase in radius significantly increases the weight of the log.

Yes, knowing the weight of the log is essential for pricing, especially when log prices are based on weight.
15. How can I use the calculator for different log lengths?
Simply adjust the log length in the input field to calculate the weight for logs of varying sizes.
16. How do I measure the radius of the log?
The radius is the distance from the center of the log to its outer edge. Measure the log’s diameter and divide by 2 to find the radius.
