1. What is a Timber Volume Calculator?

Definition: This calculator estimates the volume of timber based on length, width, and thickness using common Australian timber sizes.

Purpose: It helps carpenters, builders, and DIYers determine how much timber is needed for projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of timber (cubic meters)
• \( L \) — Length (meters)
• \( W \) — Width (meters, e.g., 0.07 for 70mm)
• \( T \) — Thickness (meters, e.g., 0.019 for 19mm)

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

3. Common Australian Timber Sizes

Details: Standard sizes include:

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

4. Using the Calculator

Tips: Enter the length in meters, width (default 0.07 m for 70mm), and thickness (default 0.019 m for 19mm). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why use meters instead of millimeters?
A: The calculator provides results in cubic meters (m³), the standard unit for timber volume in Australia.

Q2: How do I convert mm to m?
A: Divide mm by 1000 (e.g., 70mm = 0.07m, 19mm = 0.019m).

Q3: What's the actual size vs nominal size?
A: Nominal sizes (like 70×19) refer to dressed dimensions; actual sizes may be slightly smaller.

Q4: How accurate is this calculation?
A: It provides theoretical volume; actual timber may vary slightly due to milling tolerances.

Q5: Can I calculate multiple pieces?
A: Multiply the result by the number of identical pieces needed.
