What is an oil barrel?
An oil barrel (abbreviated as bbl) is the standard unit of measurement in the global petroleum industry.
Volume Equivalents
- 158.99 liters
- 42 US gallons
- 34.97 Imperial gallons
Industry Usage
- Crude oil production measurement
- International oil pricing
- Trading and futures contracts
The oil barrel is used universally across the petroleum industry worldwide, making it essential for understanding oil production statistics and market prices.
What's the difference between cm³, mL, and cc?
These three units represent exactly the same volume but are used in different contexts:
- cm³ (cubic centimeter): Scientific and mathematical contexts, emphasizing three-dimensional space
- mL (milliliter): General liquid measurement, cooking, beverages, and everyday use
- cc (cubic centimeter): Medical contexts (syringe volumes) and automotive industry (engine displacement)
Example: A 2000cc engine is the same as a 2.0L engine, and a 5cc medical syringe holds 5mL of liquid.
How accurate are the conversions?
This converter uses precise conversion factors with up to 8 decimal places of precision, which exceeds the accuracy of most physical measurements.
For practical purposes, this level of precision is more than sufficient for:
- Professional engineering calculations
- Scientific research and laboratory work
- Industrial manufacturing specifications
- Medical dosage calculations
- All everyday measurement needs
Can I convert cubic feet to liters?
Yes! Cubic feet to liters is a commonly needed conversion, especially for:
Shipping Volumes
HVAC Calculations
Aquarium Sizing
Simply select "Cubic Feet" as your source unit and "Liters" as your target unit to perform this conversion instantly.
Why do different countries use different volume units?
The diversity of volume measurement systems stems from historical development and cultural traditions:
Historical Development
Different civilizations developed their own measurement systems based on local needs, available containers, and trade practices. These systems evolved independently over centuries.
Metric Standardization
The metric system (liters) was developed in France in the late 1700s and is now the international standard, used in science, medicine, and most countries worldwide.
US Exception
The United States continues to use customary units (gallons, cups, fluid ounces) for everyday purposes, though metric is used in scientific and medical contexts.
UK Hybrid System
The United Kingdom has largely adopted metric measurements but still uses Imperial pints for beer and milk, creating a unique hybrid system.
Modern reality: This diversity means conversion tools like this one are essential for international communication, trade, travel, and accessing recipes or specifications from different countries.
How do I convert engine displacement?
Engine displacement is typically measured in either liters (L) or cubic centimeters (cc), depending on the region and vehicle type:
Common for Cars
- 2.0L engine
- 3.5L V6 engine
- 5.0L V8 engine
- Used in North America and Europe
Common for Motorcycles
- 600cc sportbike
- 1200cc cruiser
- 250cc beginner bike
- Used globally for motorcycles
Use this converter to switch between liters and cubic centimeters instantly for any engine size.
