The size of the lead (0.3mm, 0.5mm, 0.7mm, 0.9mm, 1.3mm, etc) is just the width of the lead. In a #2 pencil, the #2 refers to the hardness of the lead. This is where those little letters on the lead come into play on the lead refill packs. The ratings are like this:
(softer) (harder)
B6 B5 B4 B3 B2 B1 HB H1 H2 H3 H4 H5 H6
(darker) (lighter)
Most lead refill packs you buy from places like office max, target, bookstore, etc will be HB. Lead that comes with brand new mechanical pencils is almost always HB. This "mid-range" hardness is equivalent to #2 lead in a #2 pencil. The other kinds of lead are pretty much only sought after by drafters and you'll probably only find them in a drafting supply store or a specialty office store.
So the answer to your question: it probably is, but not because it's 0.7mm. rather, it probably is because HB lead is the most common and most likely to have come with your pencil.

What is the length of a unsharpened pencil in mm?
187 mm.
What does 10 mm in diameter look like?
A 10 mm diameter object would appear as a circle with a width of 10 millimeters when viewed directly from above. To put it into perspective, a common comparison is that a standard pencil's diameter is around 7-8 mm. So, a 10 mm diameter object would be slightly larger than a pencil's width.
What is 300 x 1800mm in inches?
300*1800 mm = 540000 mm = 21260 inches approx.This is not the same as 300 mm x 1800 mm which is a measure of an area.
Which is greater 15cm or 150mm?
Since 1 cm = 10 mm, they are the same.15 cm = 150 mm
Is 2mm larger than 3mm?
No. The units are the same (mm) so the numbers can be compared directly. 2 < 3 → 2 mm < 3 mm. → 2 mm is less than 3 mm, ie 2 mm is not larger than 3 mm.
