What is a cor (Biblical) unit?

A cor is an ancient Biblical Hebrew dry volume unit equal to 10 ephahs, commonly estimated at about 220 liters.

What does one acre-foot represent?

An acre-foot equals the volume of water covering one acre of land to a depth of one foot, approximately 43,560 cubic feet.

Why convert cor (Biblical) to acre-foot?

Converting cor to acre-foot helps translate ancient dry volume measures into modern water volume units for research in archaeology, agriculture, and water management.

Browser-based and simple to use without installation.

Examples

Convert 5 cor (Biblical): 5 × 0.0001783569 = 0.0008917845 acre-foot.
Convert 10 cor (Biblical): 10 × 0.0001783569 = 0.001783569 acre-foot.

Common Use Cases

Interpreting ancient grain or oil quantities from Biblical texts.
Reconstructing agricultural yields and storage in archaeological research.
Comparing historic economies with present-day measurement systems.
Calculating reservoir and lake storage in water resources management.
Planning irrigation water deliveries in agricultural contexts.

Tips & Best Practices

Remember the cor is an approximate ancient measure; treat results as estimates.
Account for the difference between dry volume (cor) and liquid volume (acre-foot) when comparing directly.
Use conversions to assist interdisciplinary studies that require linking ancient data to modern units.
Cross-validate historical volumetric data with multiple sources if available.
Apply the tool to facilitate contextual understanding in water resource planning.

Limitations

The cor unit has historical variability around 220 liters, affecting precision.
Acre-foot measures liquid volume, while cor measures dry volume, so direct comparisons may be imprecise.
This tool does not account for material density differences when converting dry to liquid volumes.
