What is a barrel (UK) in volume measurement?

A barrel (UK) is an Imperial volume unit equal to 36 imperial gallons, commonly used in British brewing for beer, ale, and cider.

What does a megaliter represent?

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

Can I use this conversion for barrels from other countries?

No, this conversion is specific to the UK barrel size and should not be applied to barrel units from other regions.

What Is This Tool?

This tool helps convert volume from the barrel (UK) unit, traditionally used for beer, ale, and cider volumes in British brewing, into megaliters, a metric unit that expresses large water volumes in hydrology and engineering.

How to Use This Tool?

Enter the volume value in barrel (UK) units
Select barrel (UK) as the original measurement
Choose megaliter as the target unit
Click convert to get the equivalent volume in megaliters

Key Features

Converts volume units from barrel (UK) to megaliter accurately
Supports usage in brewing, water resource management, and environmental contexts
Easy and quick browser-based conversion without installation

Examples

10 barrel (UK) [bbl (UK)] equals 0.001636592 megaliters [ML]
500 barrel (UK) [bbl (UK)] equals 0.0818296 megaliters [ML]

Common Use Cases

Sizing production batches and keg volumes in British breweries
Recording historical ale or cider barrel inventories
Converting traditional brewery volumes for hydrology and engineering projects involving large water quantities

Tips & Best Practices

Use this tool for large quantities to get meaningful megaliter values due to the small barrel-to-megaliter ratio
Ensure the barrel unit is specifically UK Imperial when converting
Apply conversions when transitioning from traditional brewing volume measures to metric units in water management

Limitations

Barrel (UK) is a small unit compared to megaliter, so conversions usually require large barrel quantities
This conversion is specific to the UK barrel and should not be used for other barrel size standards
Rounding limitations may arise from small conversion fractions typical in brewery volumes
