1. What is a Timber Weight per m3 Calculator?

Definition: This calculator estimates the weight of timber based on its volume and density.

Purpose: It helps construction professionals, woodworkers, and DIYers determine the weight of timber for projects involving wood materials.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( W \) — Weight of timber (kg)
• \( V \) — Volume of timber (cubic meters)
• \( \gamma \) — Density of timber (kg/m³)

Explanation: The timber volume is multiplied by its density to calculate the total weight.

3. Importance of Timber Weight Calculation

Details: Proper timber weight estimation ensures structural integrity, transportation planning, and accurate material budgeting.

4. Using the Calculator

Tips: Enter the timber volume in cubic meters and density in kg/m³ (default 500 kg/m³ for pine). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are typical timber densities?
A: Timber density varies by species: Pine (400-600 kg/m³), Oak (600-900 kg/m³), Merbau (600-800 kg/m³), Balsa (100-200 kg/m³).

Q2: Does moisture affect timber density?
A: Yes, wet timber weighs more than dry timber. Density values typically refer to air-dried timber (12-20% moisture content).

Q3: How do I find the volume of irregular timber?
A: For irregular shapes, use the water displacement method or approximate as rectangular volume (length × width × height).

Q4: What's the difference between density and specific gravity?
A: Density is mass per volume (kg/m³), while specific gravity compares density to water (dimensionless). Multiply specific gravity by 1000 to get approximate kg/m³.

Q5: How accurate are these calculations?
A: Calculations provide estimates. Actual weight may vary due to moisture content, resin content, and natural variations in wood.
