1. What is the Wood Weight Formula?

The Wood Weight Formula calculates the weight of wood based on its volume and specific gravity. It accounts for the density of water (1000 kg/m³) and the relative density of the wood species.

2. How Does the Calculator Work?

The calculator uses the Wood Weight Formula:

Where:

• \( Volume \) — Volume of wood in cubic meters (m³)
• \( Specific\ Gravity \) — Ratio of wood density to water density (dimensionless)
• \( 1000 \) — Density of water in kg/m³

Explanation: The formula multiplies the wood's volume by its specific gravity (relative to water) and the density of water to get the weight in kilograms.

3. Importance of Wood Weight Calculation

Details: Accurate weight calculation is crucial for transportation logistics, structural engineering, and determining the load-bearing capacity of wood structures.

4. Using the Calculator

Tips: Enter volume in cubic meters and specific gravity as a decimal (e.g., 0.65 for Douglas fir). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is specific gravity of wood?
A: Specific gravity is the ratio of wood density to water density. It typically ranges from 0.35 (light woods) to 0.85 (very dense woods).

Q2: How do I find the specific gravity of my wood?
A: Consult wood density tables or measure it by dividing the wood's dry weight by the weight of an equal volume of water.

Q3: Does moisture content affect the calculation?
A: Yes, this formula uses specific gravity values for dry wood. For green wood, you may need to adjust for moisture content.

Q4: Can I use other volume units?
A: The calculator uses m³. For other units, convert to m³ first (1 m³ = 1000 liters = 35.315 ft³).

Q5: What's the density of common wood types?
A: Examples: Balsa (0.16), Pine (0.35-0.50), Oak (0.60-0.75), Ebony (0.90-1.20).
