1. What is Wood Density?

Definition: Wood density is the mass of wood per unit volume, typically measured in kilograms per cubic meter (kg/m³).

Purpose: Understanding wood density helps in material selection for construction, furniture making, and other woodworking projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density of wood (kg/m³)
• \( m \) — Mass of wood (kg)
• \( V \) — Volume of wood (m³)

Explanation: The mass of the wood is divided by its volume to calculate density.

3. Importance of Wood Density

Details: Density affects wood's strength, durability, and workability. Higher density woods are generally stronger but harder to work with.

4. Using the Calculator

Tips: Enter the mass of wood in kilograms and volume in cubic meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density range for wood?
A: Most woods range between 300-900 kg/m³. For example, oak is ~700 kg/m³ while balsa is ~160 kg/m³.

Q2: How do I measure wood volume accurately?
A: For regular shapes, use length × width × height. For irregular shapes, use water displacement method.

Q3: Does moisture content affect wood density?
A: Yes, wet wood has higher density. Measurements are often taken at 12% moisture content for consistency.

Q4: What's the difference between green and dry density?
A: Green density includes moisture in freshly cut wood, while dry density is measured after proper drying.

Q5: Why does wood density matter in construction?
A: Denser woods are stronger and more durable but heavier, affecting structural design and transportation.
