1. What is Standard Timber Volume Calculation?

Definition: This calculator estimates the volume of timber based on standard Australian sizes (e.g., 90×45 mm, 140×19 mm).

Purpose: It helps builders, carpenters, and DIYers determine timber volume for projects and material ordering.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume (cubic meters)
• \( L \) — Length (meters)
• \( W \) — Width (meters, e.g., 0.09 m for 90mm)
• \( T \) — Thickness (meters, e.g., 0.045 m for 45mm)

Explanation: The three dimensions are multiplied to calculate the volume in cubic meters.

3. Common Australian Timber Sizes

Standard Sizes:

• 90 × 45 mm (0.09 × 0.045 m)
• 140 × 19 mm (0.14 × 0.019 m)
• 70 × 35 mm (0.07 × 0.035 m)
• 190 × 19 mm (0.19 × 0.019 m)

4. Using the Calculator

Tips: Enter length in meters, width (default 0.09 m for 90mm), and thickness (default 0.045 m for 45mm). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why calculate timber volume?
A: Volume calculations help estimate material requirements and costs for projects.

Q2: Are these sizes exact?
A: Nominal sizes may differ slightly from actual dimensions due to milling and drying.

Q3: How do I calculate for multiple pieces?
A: Calculate volume for one piece then multiply by quantity needed.

Q4: What about treated timber?
A: The calculation is the same, though weight may differ due to treatment.

Q5: How to convert to board feet?
A: 1 m³ ≈ 424 board feet (for 25mm thick timber).
