so 0dB, -14db, and +3dB are completely meaningless or inaccurate measurements on all the SSLs in major recording studios because the decibel is a dimensionless unit beyond the intellectual scope of non-mathematically trained individuals huh?
okay.
No it's not meaningless. However the way you write it makes a big diffrence so You need to include a suffix of sorts to specify what you are talking (or asking about).
For example take "0dB":
0dB
FS (Full Scale) is the highest digital level that can be reproduced. In theory with floating point you can express numbers much higher than that but since you don't want to learn about the "math" don't worry about that.
0dB
SPL (Sound Pressure Level) is the threashold of "typical" human hearing (often would be refered to as silence).
You see how "0dB" could be two completely diffent and somewhat opposing things?
Now in regards to the meter in FL studio. From what I know it's a peak meter. However thier website doesn't seem to mention what it's calibration is. I would assume that "+6dB" is actually 0dBFS and that would mean that "0dB" is -6dBFS. However I may be mistaken and "0dB" in FL studio may infact be 0dBFS because FL does use 32bit floating point and +0dBFS is in theory possible (mathematically).
But now to answer your question about loudness, which I've seen you ask time and time again. And you time and time again ignore the good advice you're given and continue to focus on something that does not matter, especially at the point you are in your understanding of audio and since
LOUDNESS IS NOT ACHEIVED DURRING THE MIXING STAGE.
On "hot" overly loud commercial releases the song is typically put through a limiter set to PEAK at or just below 0dBFS (quite often around -0.3dBFS to avoid registering as clipping at the pressing plant). If you want to really do this to your music for some stupid reason, you can.
To do so get any "brickwall" type limiter and set it's out put to around -0.3dBFS and then adjust the input threashold until your music is as "loud" as you want it to be (in theory the lower the threshold the "louder" the output). Just keep in mind that you're more than likely going to make your music sound like complete SH!T and add all kinds of distortion and make playback on most systems "risky".
Please for the sake of your future in music pick up Bob Katz Mastering Audio and in the mean time read all of his articles @

You might after doing some reading start to understand what myself and others here (like Sleepy and Moses) have been trying to get you to understand.
