* 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.
