how much does a eraser weigh? 8 Types

A standard eraser typically weighs around 5 grams. In pounds, this is approximately 0.01 pounds or 0.18 ounces. Erasers are deliberately designed to be lightweight for easy handling and erasing during everyday writing and drawing activities.

The weight of an eraser can vary slightly based on its size, composition, and intended use. Lighter erasers are often used by students and professionals who need a portable option for correcting mistakes in notes or sketches. Heavier erasers, though less common, might be chosen for specific tasks that require more precision or for artistic purposes.
