Wood Log Weight Formula:
| From: | To: |
The wood log weight formula calculates the approximate weight of a wood log based on its diameter, length, and wood density. This calculation is useful in forestry, lumber industry, and woodworking for estimating log weight without direct measurement.
The calculator uses the wood log weight formula:
Where:
Explanation: The formula calculates log weight by squaring the diameter, multiplying by length and density, then dividing by 16 to convert to pounds.
Details: Accurate log weight estimation is crucial for transportation planning, pricing calculations, load capacity assessments, and inventory management in the forestry and lumber industries.
Tips: Enter diameter in inches, length in feet, and wood density in pounds per board foot. All values must be positive numbers. Common wood densities range from 25-45 pounds per board foot depending on wood species.
Q1: How accurate is this formula?
A: The formula provides a good estimate but actual weight may vary based on wood moisture content, bark presence, and specific wood characteristics.
Q2: What are typical density values for common woods?
A: Pine: 25-30 lbs/bf, Oak: 40-45 lbs/bf, Maple: 35-40 lbs/bf, Cedar: 25-30 lbs/bf. These values vary with moisture content.
Q3: Should I measure diameter with or without bark?
A: For most accurate results, measure the inside bark diameter (actual wood diameter) unless you specifically need to include bark weight.
Q4: Can this formula be used for all wood species?
A: Yes, but you must use the appropriate density value for the specific wood species being calculated.
Q5: How does moisture content affect the calculation?
A: Moisture significantly increases wood weight. Use density values that correspond to the current moisture content of the wood.
