What Is This Tool?
This converter facilitates the transformation of volume measurements from the historical maritime unit Ton register (ton reg) into the International System volume unit Cubic meter (m^3). It helps interpret older ship capacity data in modern standardized units.
How to Use This Tool?
-
Enter the volume value in ton register units you want to convert
-
Select 'ton register [ton reg]' as the source unit and 'cubic meter [m^3]' as the target unit
-
Initiate the conversion to get the volume expressed in cubic meters
-
Use the converted value for further engineering, regulatory, or archival purposes
Key Features
-
Converts ton register volumes to cubic meters using an official conversion factor
-
Useful for maritime, engineering, and archival volume measurement translation
-
Browser-based and easy to use without needing complex calculations
-
Supports accurate expression of ship internal volume data in modern units
Examples
-
Convert 5 ton register to cubic meters: 5 × 2.8316846592 = 14.158423296 m³
-
Convert 10 ton register to cubic meters: 10 × 2.8316846592 = 28.316846592 m³
Common Use Cases
-
Interpreting historical ship internal volume from tonnage certificates or old ship plans
-
Calculating port fees, canal dues, and pilotage charges based on register tons
-
Estimating cargo hold space in archival maritime research
-
Standardizing volume measurements for engineering and logistics involving older data
Tips & Best Practices
-
Always verify the context to ensure ton register applies, especially in historical documents
-
Use the converter primarily for archival or regulatory records referencing ton register
-
Apply the conversion factor directly without rounding intermediate results for precision
-
Cross-check converted volumes against design or storage requirements for practical use
Limitations
-
Ton register is an obsolete maritime volume unit replaced internationally by the 1969 Tonnage Convention measures
-
The conversion factor is an approximation and may not fully capture older measurement variations
-
Applicability is mainly limited to historical or archival ship data and not for modern shipping measurements
Frequently Asked Questions
-
What is a ton register (ton reg)?
-
A ton register is a historical maritime unit of volume equal to 100 cubic feet, previously used to express a ship's internal capacity as gross or net register tonnage.
-
Why convert ton register to cubic meter?
-
Converting to cubic meters enables standardization of volume data in modern SI units, facilitating accurate comparisons, engineering calculations, and regulatory compliance.
-
Is ton register still used today internationally?
-
No, ton register has been largely replaced by gross/net tonnage under the 1969 Tonnage Convention and is mainly encountered in historical and archival contexts.
Key Terminology
-
Ton register (ton reg)
-
A maritime unit of volume equal to 100 cubic feet, historically used to express ship internal volume as register tonnage.
-
Cubic meter (m³)
-
The SI derived unit of volume defined as the space occupied by a cube measuring one meter on each side.
-
Gross/net register tonnage
-
Historical measures of a ship's internal volume used for commercial and regulatory purposes before the 1969 Tonnage Convention.
