What is a board foot used to measure?

A board foot measures the volume of lumber and is defined as a board 1 foot long, 1 foot wide, and 1 inch thick.

What kind of unit is a tun?

A tun is a historical English liquid volume unit used for large casks, traditionally defined as 252 wine gallons.

Can I use this conversion for precise modern liquid measurements?

No, this conversion is mostly useful for historical and archival context as tun and board foot differ in measurement types and definitions have changed.

What Is This Tool?

This converter allows you to transform volume measurements from board foot, a solid lumber unit, to tun, a historical English unit of liquid volume. It is especially useful for relating timber volume to traditional cask sizes in archival, trade, and production contexts.

How to Use This Tool?

Enter the value representing the volume in board feet you want to convert
Select board foot as the original unit and tun as the target unit
Click on the convert button to get the equivalent value in tun
Use the output to assist in your calculations, archival records, or inventory management

Key Features

Converts volume units from board foot to tun accurately based on established conversion rate
Supports understanding of both lumber volume and historical liquid cask volume measurements
Helps with archival, trade, and inventory applications involving timber and traditional beverage casks
Easy to use interface suitable for woodworking professionals, researchers, and sawmill operators

Examples

50 board feet equals 0.12368584 tun using the conversion rate 1 board foot = 0.0024737168 tun
100 board feet equals 0.24737168 tun converted with the same formula

Common Use Cases

Estimating lumber volume in traditional timber trade compared to historical cask sizes
Archival research involving old shipping records and customs documentation referring to tun units
Calculating lumber material for woodworking projects while referencing historical beverage container volumes
Sawmill inventory and production reports that link board footage to traditional liquid volume units

Tips & Best Practices

Use this conversion primarily for contextual or archival comparisons rather than precise physical volume equivalences
Be aware that the tun's size varies regionally and over time, so apply conversions with historical context in mind
Double-check archival or historical data for the specific tun definition relevant to your sources
Combine this tool with other unit converters when dealing with mixed materials or complex inventories

Limitations

The tun unit has regional and historical variations, so this conversion may not fit all older references exactly
Board foot measures solid lumber volume, whereas tun is a liquid volume measure, limiting direct physical equivalence
Changes in unit definitions over time mean modern standards might differ from historical applications
Use caution when applying this conversion to precise engineering or material calculations
