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)).[
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!
Millimeters.
The standard diameter of a pencil is about 0.3 inches or 7.6 millimeters.

The diameter of normal size pencil lead is about 0.7 millimeters.
scale factor=7/3.5=2
A standard pencil is typically about 7 millimeters in diameter, which is roughly 0.28 inches.
A typical pencil is about 7 inches long and 0.25 inches in diameter.

A 7mm pencil lead is thicker than a 5mm pencil lead. The diameter of the lead determines its thickness, so the lead with a larger diameter will be thicker.
It is twice its radius

pencils can have differend diameters,regular its about 5mm
The diameter of a standard pencil is typically around 0.25 inches or 6.5 millimeters.
