Weight of Log Formula:
| From: | To: |
The weight of a log is calculated using the mathematical formula for volume combined with the density of the wood. This calculation is essential for forestry, lumber industries, and transportation planning.
The calculator uses the following equation:
Where:
Explanation: The equation calculates the volume of the log (as a cylinder) and multiplies it by the wood density to determine weight.
Details: Accurate weight estimation is crucial for transportation planning, load capacity calculations, and commercial transactions in the timber industry.
Tips: Enter diameter in inches, length in feet, and wood density in lb/ft³. All values must be positive numbers.
Q1: Why is the diameter divided by 2 in the formula?
A: The diameter is divided by 2 to convert it to radius, which is needed for the circular area calculation (πr²).
Q2: What are typical wood densities?
A: Common densities range from 25 lb/ft³ for softwoods like pine to 45+ lb/ft³ for hardwoods like oak.
Q3: Why divide by 1728?
A: 1728 converts cubic inches to cubic feet (12×12×12), since density is given per cubic foot.
Q4: Can this be used for irregularly shaped logs?
A: This assumes a perfect cylinder. For irregular logs, more complex calculations or measurements are needed.
Q5: How does moisture content affect the calculation?
A: Wood density varies with moisture content. Use appropriate density values for the wood's current condition.
