Why storage devices have less space than advertised

The answer is whether it is fake or original it will show less space no matter what you do. So you can’t decide just by learning that you have less usable space. So what is the reason behind this, where is that extra space has gone?

Storage devices we buy have less space than advertised. Generally we get 7% less space than advertised. In real world we use decimal number system where:

PrefixValue
Kilo1,000
Mega1,000,000
Giga1,000,000,000
Tera1,000,000,000,000
Peta1,000,000,000,000,000
So on….
