1@topomorto Obviously not—if it did, it would have been 1,3 litres. ;-)– Janus Bahs JacquetCommented Oct 22, 2016 at 12:14

For straightforward expressions of volume, you would keep the 's':
Here's 1.3 liters of beer.
The volume of this beer glass is 1.3 liters.
If I drink more than 1.3 liters of beer, I like to have some chips on the side.
For use as an adjective, omit the 's':
Please give me a 1.3 liter glass of beer
here, you're using '1.3 liter' as an adjective in the same way that you might use 'large'. In this usage, some people would hyphenate to '1.3-liter': Hyphen in physical quantities before nouns?.
It's similar with meters and most units - hence you would say that in a hundred-meter race, the athletes have to run one hundred meters. You would say it that way even if you were abbreviating to '100m' too.

As and adjective, is this true ---> Three 20 year old boys Commented Oct 22, 2016 at 7:35

1'Three 20 year old boys' is correct, though you will often see hyphens in ages : 20-year-old. Some people might also put a hyphen in '1.3-liter' too : english.stackexchange.com/questions/112297/… Commented Oct 22, 2016 at 7:38

It's not just the same with metres and other measurements, but with (almost) all nouns used attributively. It's also a five-man army, but an army of five men, for instance. Commented Oct 22, 2016 at 12:16
Before the noun: a 1.5 meter wall. Otherwise: the wall is 1.5 meters long.
