What is a tun in volume measurement?

A tun is a traditional English unit of liquid volume used for large casks, historically defined as 252 wine gallons or about 954 litres, though its exact size has varied.

What does ton register measure?

Ton register (ton reg) is a maritime volume unit equal to 100 cubic feet, used historically to express a ship's internal capacity as gross or net register tonnage.

Why convert tun to ton register?

Converting tun to ton register helps translate large cask volumes into maritime terms useful for interpreting shipping, trade, and archival records involving different unit systems.

Are ton register units still used today?

Ton register units have mostly been replaced by modern tonnage measures in international maritime contexts, though they remain relevant in historical and archival analyses.

Can the tun size affect conversion accuracy?

Yes, since the tun size has changed over time and regionally, using different sources may lead to discrepancies in volume conversion results.
