It's impossible to give an exact answer to how many kilograms are in a pencil without knowing the specific pencil. Here's why:

* Pencil Size: Pencils come in different sizes (e.g., #2, mechanical pencils, jumbo pencils).

* Material: The type of wood, the lead or graphite, and any other materials used will affect the weight.

* Length: A longer pencil will weigh more than a shorter one.

Instead of kilograms, you can think of a pencil as weighing a few grams. A typical #2 pencil might weigh around 5-10 grams.
