A barrel of oil is exactly 42 gal. How many liters of oil are in a barrel?
The Correct Answer and Explanation is:
To convert gallons to liters, we use the conversion factor:
1 gallon (gal) = 3.78541 liters (L).
Given that a barrel of oil is exactly 42 gallons, we can calculate the number of liters by multiplying the number of gallons by the conversion factor:42 gal×3.78541 L/gal=158.98722 L.42 \, \text{gal} \times 3.78541 \, \text{L/gal} = 158.98722 \, \text{L}.42gal×3.78541L/gal=158.98722L.
So, a barrel of oil contains approximately 158.99 liters.
Explanation:
The gallon is a common unit of volume used primarily in the United States, while the liter is more commonly used worldwide, particularly in countries that use the metric system. To convert between these two units, we rely on the fixed relationship where one gallon is equal to 3.78541 liters. This is based on the international agreement for the U.S. gallon and liter.
The conversion process involves multiplying the given value (in gallons) by the conversion factor (3.78541 liters per gallon) to arrive at the equivalent volume in liters. In this case, the calculation is straightforward:
- Start with the number of gallons: 42 gal.
- Multiply by the conversion factor: 42×3.78541=158.99 L42 \times 3.78541 = 158.99 \, \text{L}42×3.78541=158.99L.
The result of this multiplication gives the volume in liters. This process ensures that the measurement is consistent and can be used for international trade, scientific measurements, and industry standards. By converting volumes accurately, businesses and industries that deal with oil, for instance, can easily exchange and compare volumes on a global scale.
