Question

One barrel of oil is approximately equivalent to how many litres?

• A. 200
• B. 150
• C. 120
• D. 160

Hint:

One barrel equals 42 US gallons, so convert that to litres.

Answer 1

The Correct Option is D

The question checks whether you know the standard volume used worldwide to measure crude oil.

1. 200 litres: This number is often mixed up with a standard oil drum used for storage or transport, but that is a separate measure from the barrel unit used in oil trading.
2. 150 litres: This is lower than the actual figure, so it undercounts the true barrel volume.
3. 120 litres: This is even further off and does not match the accepted conversion used by the oil industry.
4. 160 litres: One barrel of oil equals 42 US gallons, which works out to about 158.9 litres, and this rounds closest to 160 among the given options.

So option D is correct: a barrel of oil is approximately 160 litres.

Let's summarize:

• One barrel of oil is fixed at 42 US gallons.
• In litres, that comes to close to 159, rounded to 160.
• This is different from a storage drum, which usually holds 200 litres.

Keep the 42-gallon rule in mind so you don't confuse the oil barrel with a regular storage drum.
