There's an awful lot of confusion among an awful lot of people about the
terminology involved here and the way the results are expressed, so
let's take a careful look.

If we write 5%, we say five percent, meaning five parts out of one
hundred. Likewise, 1% is one percent or one part out of a hundred.

Since 0.5 is one-half, then 0.5% is one-half of one percent, meaning
five parts out of one thousand.

Now, for the purpose of an example, let's assume an adult human being
whose body contains five litres of blood. (This is in fact well within
the norm.)

Let's have this person drink some beer containing 5% alcohol. (This is a
bit on the strong side, perhaps, but not at all unusual.)

In the US, a 12-oz. bottle of beer contains 355 ml. In Europe, the
standard bottle is a little smaller, at 330 ml. Let's take the European
size, and say that a six-pack contains 1980 ml. Then, let's round that
off to 2000 ml., or two litres.

So we've got two litres of beer containing 5% alcohol, which means that
we have a total of 100 ml of 'pure' alcohol.

If our drinker were to pound down an entire six-pack of this strong(ish)
beer in a very short time, he would no doubt be drunk. How drunk? For
the sake of the example, let's assume that (a) all of the alcohol in the
beer is absorbed into the blood immediately and (b) none of it is
metabolised. That means he's got 100 ml of alcohol dispersed in 5000 ml
of blood. That means 1 part in 50, or 2%. Two percent. Written as a
decimal, that is 0.02 blood alcohol--it is NOT 0.02%.

Do you think that much alcohol is directly absorbed in the bloodstream?

Let me make it simple.
If someone was shooting alcohol directly into their veins, YOUR info
would make sense. 100 ml of alcohol into 5 liters of blood is 2 percent.
However, most people drink it and only a small percentage gets absorbed
in the blood.
