Formula: bbl = ft³ × 0.178108
Converting cubic feet to barrels is essential across petroleum, brewing, and chemical industries. With 1 cubic foot equaling approximately 0.178541 barrels (or 1 barrel equaling 5.61458 cubic feet), precision in this conversion directly impacts inventory management, pricing calculations, and regulatory compliance in these high-value industries.
Accurate cubic foot to barrel conversion is critical for petroleum pricing, where each barrel represents significant monetary value. A single conversion error of just 0.1 barrels on a 10,000 cubic foot storage tank represents approximately $7-15 in lost value depending on crude oil prices. Regulatory agencies require precise measurements for tax compliance, environmental monitoring, and international trade documentation.
Oil companies measure crude oil reserves, production volumes, and storage capacity in both cubic feet and barrels. Barrel is the standard unit for international oil trading, while cubic feet is used for reservoir calculations and tank specifications. Accurate conversion ensures correct royalty payments, trading contracts, and production reporting to regulatory bodies.
Breweries measure fermentation tank volumes, production batches, and storage capacity using both cubic feet and barrels. The beer barrel (36 gallons) differs from the oil barrel (42 gallons), so conversion context matters. Accurate measurements ensure consistent batch sizes, quality control, and production planning for distribution.

This cubic foot to barrel converter uses high-precision conversion factors to ensure accurate results for professional and academic use.
Our calculator provides results with up to 10 decimal places for maximum accuracy.
One cubic foot equals 0.178541 barrels (using the standard 42-gallon oil barrel). Conversely, one barrel equals 5.61458 cubic feet. For beer barrels (36 gallons), one cubic foot equals 0.208197 barrels. Always verify which barrel type applies to your industry before converting.
Cubic feet measure volume based on linear dimensions (length × width × height), making it practical for tank design and construction. Barrels evolved from historical shipping containers and became the standard for commodity trading because they're portable units. Different industries adopted different standards: petroleum uses barrels for trading, while engineers use cubic feet for specifications.
