A 9mm pencil lead is thicker than a 7mm pencil lead.
A 5mm lead is darker than a 7mm lead because the larger the lead size, the lighter the mark it tends to produce on paper.
The "number 2" designation refers to the "hardness" of the lead. The higher the number, the "harder" The "7mm" designation refers to the "thickness" of the lead. The higher the number, the thicker. They are not the same pencil.
.5mm is finer than .7 mm
Yes, by 2 mm (.07in).
It is 7 mm - 2 mm = 5 mm.
The standard thickness of a pencil is 7mm. However, pencils can vary in thickness depending on the manufacturer and type of pencil.
For UK diving you may still want to vary the thickness of your gear, depending on the water temperature, but for footwear, thicker is better than thinner as it will get a rougher time than most of your suit. I would say 3mm at least.
7mm is thicker than 1mm
Yes. Its small obviously, but at just over half a centimetre, it is definitely a line!! =D Yes. Do you want a line 7mm in lenght or a line that is 7mm wide (many writing pens draw lines that are 5mm & 7mm wide).
Oh, isn't that just a tiny little measurement, friend? Picture a small bead or a tiny seed - that's about how long 7mm is. It's just a wee bit bigger than the tip of a pencil, but it can still hold so much beauty and potential.
Depend on the temperature of the water. >80F none 65-79F use 5mm <65 use 7mm
