Wood Log Weight Formula:
From: | To: |
The wood log weight formula calculates the weight of a cylindrical wood log based on its dimensions and density. It assumes a perfect cylindrical shape and uniform density throughout the log.
The calculator uses the formula:
Where:
Explanation: The formula calculates the volume of the cylinder (πr² × length) and multiplies it by the wood's density to get the weight.
Details: Calculating wood weight is essential for transportation planning, structural engineering, forestry management, and commercial timber sales.
Tips: Enter radius and length in meters, density in kg/m³. All values must be positive numbers. For irregular logs, use average measurements.
Q1: How accurate is this calculation?
A: It's accurate for perfect cylinders. Real logs may vary due to irregular shapes, bark thickness, and moisture content.
Q2: Where can I find wood density values?
A: Density varies by species. Common values: Pine ~500 kg/m³, Oak ~700 kg/m³, Teak ~650 kg/m³.
Q3: Should I include bark in measurements?
A: For most purposes, measure diameter under bark. For precise calculations, specify whether measurements include bark.
Q4: How does moisture affect the calculation?
A: Use density values for the wood's current moisture content. Green wood is heavier than dried wood.
Q5: Can this be used for non-cylindrical logs?
A: For tapered logs, use average diameter. For very irregular shapes, consider water displacement methods.
