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.
Typical Typically-sized pencil under a ruler. A standard, hexagonal, "#2 pencil" is cut to a hexagonal height of 1⁄4-inch (6 mm), but the outer diameter is slightly larger (about 9⁄32-inch (7 mm)).[
A standard number 2 pencil typically measures 7.5 inches in length when unsharpened. The diameter of the pencil is generally around 0.3 inches. This size is commonly used for standardized tests and general writing purposes.
An ordinary pencil is one example.
Ah, the distance across the end of a pencil is what we call the diameter. It's the measurement from one side of the pencil to the other side, passing through the center. Just imagine a little circle that fits perfectly on the end of your pencil – that's the diameter!
