h pencils have harder lead, and they don't smudge easily and your lines are light-colored. Your b pencils have soft, black lead, and they are used for blending and shading when drawing. The higher the number for your b pencils, the darker your lead and lines are going to be.
HB refers to the hardness of the pencil. In the scale H is used for harder pencils (H for hard) HH HHH HHHH all get progressively harder, and B (the B stands for black) BB BBB BBBB get progressively softer. HB pencils (#2 on the US pencil-hardness scale) are right in the middle, so the HB stands for Hard Black.
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.

T B and H are consonants. The letter E is a vowel.
B****H
With pencils H stands for hard, B for black (soft), HB is between the two.
Pencils with H are harder, pencils with B are softer. The higher the number with the H, the harder the lead (usually light, very precise line). Pencils with B are softer, and the higher the number, the softer the lead (very dark, blurs easily).
No, 4B pencils and 4H pencils are not the same. The "B" in 4B stands for "black," indicating a softer lead that produces a darker mark, while the "H" in 4H stands for "hard," indicating a harder lead that produces a lighter mark. The grading scale for pencils ranges from H (hard) to B (black), with F (fine point) in between, so 4B is much softer than 4H.
Pencils are all marked on a European system called the degree scale where H is hardest and B is blackest.Pencils can be marked as;9H, 8H, 7H, 6H, 5H, 4H,3H,2H, H F,HB, B, 2B, 3B, 4B ,5B ,6B ,7B ,8B ,9BH pencils have a higher concentrate of clay than graphite, whereas the B pencils have a much lower percentage of clay.The B pencils make soft, dark marks, whereas the H pencils have a much harder, lighter mark.The F pencil stands for fine point, which is slightly harder than the HB making it a good writingpencil.
The order of art pencils from lightest to darkest typically goes from 9H (lightest) to 9B (darkest). The "H" pencils are hard and produce light marks, while the "B" pencils are soft and create darker marks.
The difference between h and o is that h has a hu sound o has an oh or an oo sound.
Pencils are graded H (Hard) or B (Black). Hard pencils are best for fine lines (such as a draughtman might use), Black pencils are better for most types of drawing (and for shading in). An all purpose pencil is HB (just in the middle), but you can usually find H, 2H, 3H, 4H, B, 2B, 3B, 4B - and sometimes even higher numbers.
HB refers to the hardness of the pencil. In the scale H is used for harder pencils (H for hard) HH HHH HHHH all get progressively harder, and B (the B stands for black) BB BBB BBBB get progressively softer. HB pencils (#2 on the US pencil-hardness scale) are right in the middle, so the HB stands for Hard Black.
They are described by the famous Pythagoras theorem, if "a" and "b" are the legs and "h" the hypotenuse, then h x h = (a x a) + (b x b) Also a = h x sinB (where B is the internal angle (of the triangle) between the hypotenuse and side b and b = h x sinA (where A is the internal angle (of the triangle) between the hypotenuse and side a
There is a great difference between S Typhi O and H. The S Typhi O is somatic, and H is flagella.
The shades of graphite pencil from lightest to darkest are typically categorized as 9H (lightest), 8H, 7H, 6H, 5H, 4H, 3H, 2H, H, F, HB, B, 2B, 3B, 4B, 5B, 6B, 7B, 8B, 9B (darkest). The 'H' pencils are harder and lighter, while the 'B' pencils are softer and darker.
