How to Convert Metric to Board Feet
Converting metric lumber measurements to board feet is essential for international projects and working with North American lumber standards.
Measure in Metric
Measure your lumber in centimeters, millimeters, or meters. Our calculator accepts mixed units - you can use different metric units for length, width, and thickness.
Automatic Conversion
The calculator automatically converts your metric measurements to inches using precise conversion factors, then calculates board feet using the standard formula.
Get BDFT Results
Receive accurate board feet calculations with imperial equivalents displayed for reference. Perfect for international lumber projects and cost estimation.
Conversion Process
Inches = cm ÷ 2.54 | mm ÷ 25.4 | m × 39.37
BDFT = (Length × Width × Thickness in inches) ÷ 144
This two-step process ensures accurate conversion from any metric measurement to North American board foot standards.
International Applications
Import/Export

Frequently Asked Questions
How do you convert metric measurements to board feet?
First convert metric to inches: divide cm by 2.54, divide mm by 25.4, multiply meters by 39.37. Then calculate board feet using the standard formula: BDFT = (Length × Width × Thickness in inches) ÷ 144. Our calculator does all conversions automatically.
What metric units can I use with this board foot calculator?
Our calculator accepts centimeters (cm), millimeters (mm), and meters for length measurements. Width and thickness can be entered in centimeters or millimeters. All units are automatically converted to inches for accurate board foot calculations.
Why convert metric lumber measurements to board feet?
Board feet (BDFT) is the standard lumber measurement in North America for pricing and volume calculations. International projects often require converting metric lumber dimensions to board feet for cost estimation, material planning, and compatibility with North American suppliers.
How accurate is the metric to board foot conversion?
Our converter uses precise conversion factors: 1 inch = 2.54 cm exactly, 1 inch = 25.4 mm exactly. Results are calculated to 2 decimal places for maximum accuracy in professional lumber calculations and international trade applications.
Can I see both metric and imperial measurements together?
Yes! Our calculator displays your original metric inputs alongside the converted imperial measurements and final board feet result. This helps verify conversions and provides reference for both measurement systems in international projects.
