About lumber & wood tools
When working with lumber, the biggest challenge is keeping measurements consistent across different systems. A builder might receive logs described in inches but need to calculate volume in cubic meters, or a DIYer might misread a board foot calculation and end up with too little material. The tools in this category solve that problem by converting between the many units used in woodworking, from board feet and board meters to log scale and cubic volume. They remove the guesswork from material estimation and help ensure that every piece fits the plan.
Before choosing a converter, it helps to know the most common units you will encounter. Board foot is a volume measure used for rough lumber, calculated as length times width times thickness divided by 144. Log scale estimates the board foot yield from a log's diameter and length, accounting for waste. Metric lumber uses cubic meters or board meters. A frequent mistake is treating these units as interchangeable without adjusting for the thickness or the log's taper. Using the right converter for your unit type prevents ordering errors and reduces waste on site.

Unit Conversion
The Log Scale Converter handles the translation between raw log dimensions and estimated board foot output, which is essential when ordering raw logs or calculating yield. The Lumber Volume Converter works with finished dimensions, turning inches or centimeters into cubic units for total project volume. The Metric Lumber Converter bridges the gap between imperial and metric systems, allowing users to switch between board feet, board meters, and cubic meters without manual calculation.
Questions
Lumber & Wood FAQ
- How do I convert board feet to cubic meters?
- Board feet measure lumber volume based on a 1-foot length, while cubic meters measure total volume regardless of length. To convert, multiply the board foot count by 0.00236. This accounts for the thickness and the fact that board foot calculations assume a standard rough-lumber dimension.
- What is the difference between log scale and actual board foot count?
- Log scale is an estimate of how many board feet can be recovered from a log, factoring in the log's taper and expected waste during milling. Actual board foot count depends on the exact dimensions of the boards cut from that log. The Log Scale Converter gives you a starting point for ordering, but the final count comes from the mill's tally.
- Can I use these tools for metric lumber sizes?
- Yes. The Metric Lumber Converter handles the switch between imperial units like board feet and metric units like board meters. Input the value and select the units you have and the units you need, and the tool will apply the standard conversion factor without requiring you to look up formulas manually.
- Why do my volume calculations not match the supplier's quote?
- Suppliers often use different measurement standards—some quote by board foot, others by cubic meter, and some by log scale. If you input dimensions in inches but the supplier quotes in metric, or if you use a general volume calculator that ignores lumber-specific factors like taper, the numbers will diverge. Using the Lumber Volume Converter with the correct unit type helps align your estimates with the supplier's method.
- Do I need to know the log's taper to use a log scale converter?
- Most online log scale converters ask for the small-end diameter, large-end diameter, and length. If you only have one diameter, the tool will apply an average taper rate. For high-precision ordering, measure both ends of the log and enter those values so the estimate reflects the actual shape.
