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.
Metres are a measure of distance and not weight, so therefore it cannot be converted. You can have a 1.73 metre tall black of lead and a 1.73 metre tall marshmallow, they wont weigh the same.
a square foot of lead has no weight since it has no thickness
The mass of the lead will depend upon the density of the lead which depends upon the temperature of the lead. Assuming near room temperature the density of lead is 11.34 g/ml. density = mass / volume → mass = volume × density = 100 ml × 11.34 g/ml = 1134 g.
water has less density than lead. Mass depends on its volume

In some cases, when governments or regulatory bodies set a maximum price for a good, this leads to black markets. To be effective, the maximum price has to be below the market price that prevails as a result of the interaction of demand and supply.
