Tips & Best Practices

Ensure you understand the historical context since ton register and tun sizes may differ by source or region.
Use this conversion mainly for historical or comparative work rather than precise modern measurements.
Cross-reference converted volumes with original documentation for validation.

Limitations

Tun unit sizes have varied regionally and historically, potentially causing variability in conversion accuracy.
Ton register has been largely replaced by modern tonnage conventions and may not match current standards.
Conversions are approximate and best suited for historical or comparative analyses, not precise calculations.
