1. What is the Log To Firewood Calculator?

The Log To Firewood Calculator estimates the volume of firewood that can be obtained from a log based on its dimensions. It calculates both cubic feet and standard cord measurements for accurate firewood estimation.

2. How Does the Calculator Work?

The calculator uses the cylinder volume formula:

Where:

• \( \pi \) — Mathematical constant (approximately 3.14159)
• \( r \) — Radius of the log in inches
• \( L \) — Length of the log in inches
• 1728 — Conversion factor (12³) to convert cubic inches to cubic feet
• 128 — Cubic feet in a standard cord of firewood

Explanation: The formula calculates the cylindrical volume of the log and converts it to standard firewood measurements.

3. Importance of Firewood Calculation

Details: Accurate firewood estimation is crucial for heating planning, commercial firewood sales, and efficient wood stove operation. Knowing cord measurements helps in pricing and inventory management.

4. Using the Calculator

Tips: Measure the radius at the center of the log for most accurate results. Enter dimensions in inches. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a standard cord of firewood?
A: A standard cord is 128 cubic feet of wood, typically stacked as 4' x 4' x 8'.

Q2: How accurate is this calculation for irregular logs?
A: This assumes a perfect cylinder. For irregular logs, take multiple measurements and average them for better accuracy.

Q3: Does this account for bark and air space in stacked wood?
A: No, this calculates solid wood volume. Actual stacked cord volume will be less due to air space between pieces.

Q4: What's the difference between a full cord and face cord?
A: A face cord is typically 4' high x 8' long but only as deep as the wood is cut (usually 16-24 inches), while a full cord is 4' x 4' x 8'.

Q5: How should I measure log radius?
A: Measure the diameter at the center of the log and divide by 2 for the most accurate radius measurement.
