A tun is a traditional English liquid volume unit historically used for large casks, approximately equal to 252 wine gallons or around 954 litres.

What does a megaliter represent?

A megaliter is a metric unit equal to 1,000,000 litres, commonly used to express large water volumes in hydrology and engineering.

Can I use this conversion for precise volume calculations?

No, because the tun varied historically and the megaliter scale is large, this conversion is best for approximate and comparative purposes.

Common Use Cases

Translating historical wine or ale cask volume records into metric units
Converting old brewery or distillery liquid measures for archival or engineering work
Comparing historical liquid cargo quantities with modern water reservoir volumes
Environmental studies involving large scale water volumes and hydrology
Municipal water supply and treatment capacity assessments

Tips & Best Practices

Use this conversion when approximate volume equivalences are sufficient
Cross-check historical source definitions as tun size varied regionally
Apply results primarily for comparative or archival analysis rather than precision measurement
Confirm unit selection carefully before converting

Limitations

Tun size varied historically by region and over time, affecting exact equivalences
Minor discrepancies may arise due to tun approximations and large megaliter scale
Not recommended for applications requiring precise volume measurements
Conversion is intended for approximate understanding and comparative purposes
