Oil Barrel vs Cubic Metre: which is bigger?
A cubic metre is the larger unit: one cubic metre equals 6.289811 oil barrels. Put another way, you need 6.289811 oil barrels to make a single cubic metre.
What is a Oil Barrel? History, origin and usage
The 42-gallon oil barrel was fixed in 1866 when early Pennsylvania oil producers meeting in Titusville agreed on a standard, basing it on the roughly 40-gallon whiskey barrel and adding two gallons so any measuring error favoured the buyer. The abbreviation bbl actually predates the petroleum industry, having long been a shipping shorthand for barrels of goods such as fish, rum and whale oil.
The barrel is the global unit for pricing and trading crude oil, with benchmarks such as Brent and West Texas Intermediate quoted in dollars per barrel, and OPEC production set in barrels per day. It is fundamental to the energy industry and financial markets.
Almost no oil is actually shipped in physical 42-gallon barrels today; crude moves through pipelines and tankers, and the barrel survives only as a unit of account. A popular but disputed story links bbl to the blue barrels once used by Standard Oil.
What is a Cubic Metre? History, origin and usage
The cubic metre is the coherent SI unit of volume, built directly from the metre that the French Academy defined in the 1790s as a fraction of the Earth's meridian. As a derived unit it needs no separate definition: it is simply the volume of a cube one metre on each side.
The cubic metre is the standard unit for large volumes: water and natural-gas utility billing, concrete and excavation in construction, freight and shipping-container capacity, and air-handling in HVAC engineering. Scientists and engineers use it as the base volume unit in SI calculations.
A cubic metre of fresh water has a mass of about one tonne, a convenient coincidence rooted in the original definition of the kilogram. The cubic metre is sometimes called a kilolitre, and when used for stacked firewood it is known as the stère.

Tips for converting Oil Barrel to Cubic Metre
- To go from oil barrel to cubic metre, multiply by 0.1589873; to go back, divide by 0.1589873 (or multiply by 6.289811).
- For a quick mental estimate, remember that 1 oil barrel ≈ 0.1589873 cubic metre, so 10 oil barrel ≈ 1.589873 cubic metre.
- The converter above keeps full precision; the tables round for readability, so use the tool for exact figures.
- Both fields update live as you type — change either side to convert in that direction.
How to use this Oil Barrel to Cubic Metre converter
Type a number into the Oil Barrel field and the equivalent in Cubic Metre appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Cubic Metre field to convert the other way (cubic metre to oil barrel). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 bbl = 0.1589873 m³), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for oil barrel-to-cubic metre conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Watch the system: a <strong>US</strong> gallon, quart, pint and fluid ounce are <strong>not</strong> the same size as the <strong>imperial (UK)</strong> ones — a US gallon is 3.785 L while an imperial gallon is 4.546 L, and a US fluid ounce (29.57 mL) is slightly larger than an imperial fluid ounce (28.41 mL). The units on this page are labelled US or Imperial so the result is unambiguous.
