How Littres in a Drum of kerosene?

Answer 1

Obviously, this depends on the size of the drum :-)

You can get small drums for domestic use, say 2 or 4 litres.

Then there's industrial sizes, which could range from 20, 25 litres upwards.

But here's the answer I suspect you might be looking for: 205 litres is a common size for things like Diesel, Kerosene, etc. that's because it's equivalent to 44 gallons (as in "44 gallon drum").
