The number refers to the "hardness" of the pencil's lead.
A little more in depth.The number two refers to the hardness of the graphite core and thus the darkness of the line produced.The #2 has become the standard for all those "colour the square tests" marked by computer scanner. The #2 was chosen because they are the cheapest.
They are the cheapest because they are the most common pencils used in schools.

How many trees are used to make 2 billion pencils?
To calculate the number of trees used to make 2 billion pencils, we need to consider that on average, one tree can produce about 170,000 pencils. Therefore, to make 2 billion pencils, we would need approximately 11,765 trees (2,000,000,000 pencils / 170,000 pencils per tree). This calculation assumes standard industry practices and may vary depending on the type and size of trees used in pencil production.
How many pencils are in 1.00 moles of pencils?
The number of pencils in 1.00 moles of pencils can be calculated using Avogadro's number which is approximately 6.022 x 10^23. So, in 1.00 moles of pencils, there would be approximately 6.022 x 10^23 pencils.

If the number 2 pencil is the most popular why is it still number 2?
Because it can't print fast enough to beat number 1. The #2 pencils are so labeled because their darkness and hardness approximates those of a US classification (previously French and British) of graphite pencil leads. They are hard enough to resist breakage and soft enough to make a clear mark. Generally the harder a pencil is, the sharper the point can be, and hard pencils usually make dim marks. You can buy #1 pencils (softer and darker) and #3 pencils (harder and not as dark), and even #2.5 which indicates you are getting a slightly harder, less distinct graphite. Colored pencils tend to be softer and drawing pencils tend to be harder. (see the related link for more)

How many pencils are made each year?
ABOUT 100,000,000 (one hundred million) pencils are made in the united states every year. would you like to find out how many pencils are made per second? use a calculator. divide the number by 365 and divide that number by 24, then divide that by 60, and then divide it by sixty again. that number will be the estimated number of pencils per minute. the answer could be a fraction, because I don't know I've never done it. Acually if you do that equation I believe it gives you the number of pencils made every second.
