1. What is a Timber Weight Calculator NZ?

Definition: This calculator estimates the weight of timber in New Zealand based on its dimensions and density.

Purpose: It helps builders, carpenters, and DIYers determine timber weight for construction, transport, and structural calculations.

2. How Does the Calculator Work?

The calculator uses the formulas:

Where:

• \( V \) — Volume of timber (cubic meters)
• \( L \) — Length of timber (meters)
• \( W \) — Width of timber (meters)
• \( H \) — Height/Thickness of timber (meters)
• \( \rho \) — Density of timber (kg/m³)
• \( m \) — Mass/Weight of timber (kilograms)

Explanation: First calculate the volume from dimensions, then multiply by density to get weight.

3. Importance of Timber Weight Calculation

Details: Accurate weight estimation ensures proper structural support, safe transport loads, and correct material purchasing.

4. Using the Calculator

Tips: Enter dimensions in meters (convert from mm by dividing by 1000). Default density is 600 kg/m³ (typical for pine). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density for NZ timber?
A: Radiata pine ~500-600 kg/m³, Douglas fir ~550-650 kg/m³, native timbers 600-1200 kg/m³ (varies by species and moisture).

Q2: How do I convert from mm to m?
A: Divide mm values by 1000 (e.g., 100mm = 0.1m). The calculator works in meters.

Q3: Does this account for moisture content?
A: No, use appropriate density values for your timber's moisture condition (green vs dry).

Q4: How accurate is this calculation?
A: It provides theoretical weight. Actual weight may vary due to moisture, bark, and irregularities.

Q5: Can I use this for engineered wood products?
A: Yes, but use the specific density for the product (e.g., LVL ~600-700 kg/m³).
