Reading about buses, processors and memories being n bits wide makes me
wonder: how wide is one bit?

One bit is one bit wide.

   That's pretty much it.  If you need expansion, you have
to rely on the height.  You can get some code efficiency
with your semaphores if you store the P/V status in the
upper half of the bit, and a tasks-waiting flag in the lower
half.

   Atmel ATmega processors support this really well with the
BRHS and BRHC instructions:  Branch If Half Carry Flag Set
and ..Clear.

Shoot, I never realized the possible height of a bit. I see some
opportunities here...

  Where have you been ? - have you not seen that newest flash
stores FOUR levels per programming FLASH bit ? ((Intel et al )

That means we should start talking about QUARTER BITS.
  Those in the USA should be comfortable with this fractional notation,
as they already use both Bit and Quarter in currency.

But what if you need to test the OTHER half of the carry flag,
clearly, they forgot the orthogonal opcodes :

  BROHS :  Branch If Other-Half Carry Flag Set
  BROHC :  Branch If Other-Half Carry Flag Clear

Longer term research shows it has not stopped here :

Imagine what THAT will do to the Processor Opcodes ?

Often shortened to "quits".

The confusing thing is that a monetary bit is a half of a
quarter, where a computer bit is four quarters.

Which would be par for the course for the antiquated measurement system
still in use here in the US.

Not completely true, with ARM processors having shadow registers
for the PSR, you have to wonder about the depth of a bit as well.
Pushing/popping  PSR registers on the stack, forces you to introduce time,
the fourth dimension.

It's equal to the width of 1,000,000 microbits.

Regarding the troll season, is it 1,000,000 µbits, 1,000,000 µibits,
1000 mbits, 1024 mbits, 1,024,000 µbits or 1,048,576 µbits wide :-).

Maybe you are searching for http://www.bitburger.de/index.php?id92 %

This Bit is approximately 7cm wide and 20cm high.

Apparently, a 1 bit is 0.2280".  I can't seem to find a 0 bit in my
table of Numbered, Fractional, and Lettered Twist Drill Bit Sizes...

A Quantum bit (called a Qbit) has three states, so it is 1.5 bits
"wide".

No one has yet addressed the size of virtual bits, imaginary
bits and shadow bits.
