I just discovered there was a "imperial system"-like thing for pencils, just to make things simpler. Cool. Now stop using this.

The real reason is that Scangrade The Magnificent, a test grading/world domination device, uses lead from the number 2 pencil as it's energy source and after 50 years of testing his power will finally be great enough to take over the world.
Yes, I took selected art classes in high school and majored in Fine Arts and Visual Communications in college; so, I'm quite familiar with the different "H", "B" and "HB" grades of drawing pencils. Charcoal and pastel crayons have similar gradings for the relative darkness when applied to a given surface or how course or fine its grain is in reference to the former or how saturated or diffused the color is for the latter.

hahah nope my school's machines failed every student in school and we all used 2b pencils but the machines were really trashy at detecting the marks and the highest score anyone got was 54. teachers had to remark every single student's answers for all the subjects but those low scores were still kept in our reports.

In the 8th grade everyone was taking a state standardized test and the guy behind me bubbled everything in pen and then ripped his answer document in half. I was horrified.

We actually use 2B pencils in Australia for exams. Not HB (number 2 as you Americans call it). 2B pencils are softer and hence darker. Pretty sure other countries use 2B pencils too.

Does anyone else use scantrons in school? I hate them! They are SO annoying!
What if I want to use a 9B pencil and a kneaded eraser? Why can't I do that? It's darker than a No. 2 pencil, and since I'm the only one at my school with enough sense to wear a pair of Artist gloves when I draw or write, no one can do the sameas me(smudgy lines. Very smudgy lines)

Even types of penciles have to be named differently in the US and differently in the rest of the world. Are you doing this deliberately?

Pssshhh.. Once when I was in 7th grade we had to take a stupid muscle test in gym, I didn't have a number 2 pencil so I used my mechanical pencil, it still worked. So suck it teachers who freak out if you're using a mechanical pencil!
