The # is reference to the hardness of lead A number 2 pencil is averagely hard aka HB
The "number 2" designation refers to the "hardness" of the lead. The higher the number, the "harder" The "7mm" designation refers to the "thickness" of the lead. The higher the number, the thicker. They are not the same pencil.
The number of the pencil is based on the type of carbon lead used inside. The thicker the carbon lead gets the higher the number of the pencil becomes. If you notice a mechanical pencil is 0.9mm in diameter so it would be called a #0.9 pencil. A #2 pencil's lead is 2mm in diameter. So Why would we call a pencil a #3 pencil? Because it's lead is 3mm in diameter.
yellow?
The number two in reference to a pencil denotes the relative hardness of the graphite or "lead" that is in the pencil, HB being softer and three being harder, etc.
The 2 is the number of the lead in the pencil.
2

Theoretically, the a number 2 pencil can write an infinite number of words. The number 2 in the number 2 pencil actually indicates how hard the graphite is. For more information, visit: http://en.wikipedia.org/wiki/Pencil_hardness#Grading_and_classification
A #2 pencil will usually have the number 2 on the barrel, near the eraser end.

A leadholder-type pencil that the company called the "Stop Gauge" Pencil. There were 2 patents in 1879: number 213,569, issued on March 25, and number 215,521, issued on May 20. Both were issued to Joseph Hoffman.
It has to do with the kind of graphite or material used as the lead for the pencil.
Yes!!!

I needed a number 2 pencil. Stella penciled the appointment into her datebook. The pencil was chewed on. I lost my only pencil.
a number two pencil is made of wood with graphite in the center of it
