1. What is a Timber Weight per m3 Calculator?

Definition: This calculator determines the unit weight (density) of timber based on its mass and volume.

Purpose: It helps woodworkers, builders, and engineers calculate the density of timber for material selection and structural calculations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \gamma \) — Unit weight (kg/m³)
• \( m \) — Mass of timber (kg)
• \( V \) — Volume of timber (m³)

Explanation: The mass of timber is divided by its volume to determine its density or unit weight.

3. Importance of Timber Unit Weight Calculation

Details: Knowing timber density helps in structural design, material selection, transportation planning, and cost estimation.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's a typical unit weight for common timber?
A: Softwoods typically range 400-700 kg/m³, hardwoods 600-900 kg/m³, varying by species and moisture content.

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

Q3: Does moisture content affect the result?
A: Yes, timber weight increases with moisture content. Specify if measuring green or dried timber.

Q4: How does this differ from specific gravity?
A: Unit weight includes voids in the wood, while specific gravity compares wood density to water density.

Q5: Why is unit weight important in construction?
A: It affects structural load calculations, transportation costs, and material handling requirements.
