What is the US cup measurement in milliliters?

The US customary cup equals exactly 236.5882365 milliliters and is commonly used for culinary ingredient measurements.

Why is the tun unit important historically?

The tun was used for large liquid volumes in wine and ale casks and appears in historical inventories, trade records, and taxation documents.

Can I use this converter for precise cooking measurements?

Because the tun is a large unit and varies historically, conversions yield very small fractions and may not suit precise culinary usage.

What Is This Tool?

This converter transforms volume values measured in US customary cups into the traditional English unit called a tun, which was historically used for large liquid casks. It helps relate modern kitchen or recipe volumes to large-scale historical volume measurements.

How to Use This Tool?

Enter the volume value in cup (US) units.
Select cup (US) as the input unit and tun as the output unit.
Click the convert button to see the equivalent volume in tuns.
Use the conversion results for culinary scaling, historical research, or archival documentation.

Key Features

Converts volume from cup (US) to tun based on the modern approximation of tun size.
Supports understanding of historical and industrial volume units.
Browser-based and easy to use for both casual and professional users.
Provides accurate unit definitions and practical use cases.

Examples

4 cups (US) equals approximately 0.0009920636 tun.
10 cups (US) equals approximately 0.002480159 tun.

Common Use Cases

Measuring ingredients in US recipes and converting them into traditional large-volume units.
Interpreting historical trade and shipping volumes involving large liquid casks.
Assisting brewing and distilling industries with archival and engineering volume conversions.
Scaling recipes or industrial processes referencing English volume units.

Tips & Best Practices

Remember the tun size varies historically; treat conversions as approximate for archival work.
Use the tool primarily for bridging small kitchen measurements to large, traditional volume units.
Validate results when dealing with old records due to possible regional size differences in the tun.
Consider volume context to ensure meaningful conversion between culinary and large-scale units.

Limitations

The tun's size has changed regionally and over time; the converter uses a modern estimate (~954 liters).
Converted values from cups to tuns can be very small and may lack practical significance in cooking.
Non-standard tun sizes in historical documents mean variations in conversion accuracy.
Not suitable for precise measurement needs where standardization is required.
