Well, there has been a public debate on my server and people have been saying this -

"Count bedrock as 0 and count up"

"No, press F3 and it clearly says that Bedrock is 6. You're not counting right."

I just wanted to ask you guys what you think is the correct way

i tend to mine at bedrock level i always have better luck there but when i do mine on specific levels i use F3

This is what everyone on my server does.

F3 will tell you the Y coordinate of your eyes, which is approximately 1.62 units above the block you are standing on. Layer 0 is filled with bedrock (except for where it isn't), and bedrock appears up to layer 4. So if you are standing on the highest bedrock block, your body occupies layers 5 and 6, and your eye level is at Y = 6.62.

A picture if it helps:

[]  []   []  6
[]  []    [] 5
[]  []    [] 4
[] 3
[]      2
[]    []  1
0

The same thing happens in the floor of the Nether. The Nether ceiling looks the same but reversed: bedrock fills layer 127 and occurs down to and including layer 123.

Bedrock is generated uniformly at random with a chance of (5 - layer) / 5, so 100% at layer 0, 80% at layer 1, ... 20% at layer 4. Similarly in the ceiling of the Nether.

Negative. A block being "in layer 1" occupies the space of 1.00 up to 2.00. See my schematic above: your head is in "layer 6", so it is somewhere in between 6.00 and 7.00.

The bottom of the world is 0.00, the top of the world is 128.00, so the highest a block can be placed is layer 127 and it will occupy the space between 127.00 and 128.00.

You're quite correct; my mistake.

I always thought that the top bedrock pieces were layer 5 after notch fixed the hole to nothingness bug. so i always counted minecraftdude to be 1,62 meters tall. (this fits the visual observation that minecraftdude is shorter than 2 blocks.)
not 2,62. that would have blocked him from entering a 2 meter tall tunnel.

Since F3 show you to be at layer 6.62 it's easy to think of him as standing on top of layer 5. I think the numbering of a full layer only occurs in the line between layers.
So layer 0 is actually not a layer at all. it's just the bottom of layer 1.

My evidence for this: look at you x and z coordinates when looking straight down. notice how you pass through a round number position wise only when you look straight down on a line intersection between blocks. I tried to mark position 0,0 once and found that i needed 4 blocks to do this since there is no 0,0 block. only a 0,0 block intersection.

drawing for clarity:
[]      and block 7. but minecraftdude is not 2 meters tall. so it shows the layer below + 62. that is 6.62
[]      <- this one is therefore block 6
<- Y= 4 to 5
<- Y= 3 to 4
<- this one is between the y= 2 and y= 3
<- this block is between Y= 1 and y= 2
< this block is y:0 on the bottom and y=1 on it's top intersection plane.
[]  []
[]  []

[*:2ptr0xs1]Press F3.
[*:2ptr0xs1]Subtract 1 and remainder.
[*:2ptr0xs1]???
[*:2ptr0xs1]You now have the current layer!

I dig down to the bottom level of bedrock and count the one underneath me as 1 and count up.

If I'm too lazy and don't want to press F3, I dig down to bedrock and the FIRST bedrock block that I see is layer number 5 considering there are 5 layers of bedrock until the next block would be the end of the world. Then I climb up one and that one will be 6... etc...

And that's easier than pressing one button?

I use Zan's minimap mod, turn "display coordinates" on, and read it from there...

[EDIT] Alternatively, F3...

Using a test map whic is 100% flat with a single layer of bedrock at the absolute bottom. Standing on top of this layer while pressing F3 has a y cord of 2.62. So in plain English it means: The floor is layer 1, the body occupies layer 2 and 3, with a roof at layer 4.

Your name, logical understanding of the layers in Minecraft, and post count fit together perfectly. Well done, my friend.

People count from bedrock up because it's hard to measure from the sky.

debatable.

i call "layer 0", "layer 1" instead.  this simplifies the use of the F3 function(you dont have to subtract 1 AND drop the remainder like an above poster mentioned, you simply drop the remainder).  how can you have a "layer 0" anyway??  its actually "layer >0", the block merely begins at the y-coordinate 0.00.

while neither method is technically wrong, youre saying that the world is generated from layers 0-127.  id say its from layers 1-128, which makes more sense, generally speaking.

the layer i am on is the one myt head is at truncated,  so if i press f3 and it come y=12.6  i say i am on layer 12! it is close enough, i do not need to be too accurate someone digging down to kill me will find me no matter if i am actully on the 11 layer,
