Let us look at the popular gravel sizes or grades. Crushed stone #1: 2″-4″ wide. Crushed stones #1 measures 2-4 inches wide or in diameter. They are the largest crushed rocks, and you have to work with them individually, i.e., their size doesn't allow shoveling. Some of the places to use gravel #1 include:

The second graphite grading scale is known as the HB scale. Most pencil manufacturers outside of the U.S. use this scale, using the letter "H" to indicate a hard pencil. Likewise, a pencil maker might use the letter "B" to designate the blackness of the pencil's mark, indicating a softer lead.

The more graphite a pencil has, the softer its lead, and the darker the mark it will make. Pencil grades are indicated by letters and numbers. The standard pencil grading system goes from 9H (the hardest) to 9B (the softest), with HB being the middle point. The letter "H" stands for hardness, while the letter "B" stands for blackness.

Pencil Grades. The letters on a pencil will tell you its level of hardness or softness. For example: H: Hard F: Fine Point HB: Hard Black B: Black. Hard pencils produce light lines while soft pencils produce dark lines. Why? Because soft pencils deposit more graphite onto your drawing surface. The softer the pencil, the smoother the graphite.
