What is the full form of HB pencil?

Answer 1

If you mean what HB stands for, it's an indicator for the hardness (H) or softness (B) of the graphite and clay used.

However, the B is for blackness so HB is like average/medium grade so the full form would be Hard Black, Hard and Black, or Hard Blackness.

If you check out pencils like 3H, you'll notice that the tone when writing or drawing is light compared to an HB. Conversely, a 3B pencil will give you a darker tone.

Answer 2

the h and the b are spread apart more

AnswerThere isn't any difference, HB or H B always stands for 'hard black'. Softer pencils have 2B, 4B, 5B etc, where the higher the number means the softer (and therefore less black) the pencil. Answerone is the shade of a pencil the other is just two letters spaced out

Answer 3

In pencil classification, H stands for hardness and B for blackness. HB therefore refers to a pencil that is "Hard black"; one degree of hardness and one degree of blackness. The scale runs from 9H (very hard) to 9B (very soft/black) with HB as the central grading. This scale also includes "F" referring to "Fine Point".

Answer 4

H stands for hardness and B stands for blackness this is how a pencil scale goes:

9H 8H 7H 6H 5H 4H 3H 2H 1H H HB B 1B 2B 3B 4B 5B 6B 7B 8B 9B

9H is very fine hard and light but 9B is thick black and very soft (more like charcoal)

Answer 5

H = Hardness, and B = Black. Pencils are graded from 9H to 9B. HB is the 'middle' rating. Going away from HB, they would be graded 2H & 3H, or 2B & 3B etc.

Answer 6

It is an acronym for 'hard black.'
