9mm
it seriously depends, like maybe smaller than 3mm or larger than 7mm, it depends
This is a complicated problem. But I can do it !Energy of single photon energy = (h) (c) / (wavelength) = (6.626 x 10-34 J-s) (299,792,458 m/s) / (600 x 10-9 m)= 3.3107 x 10-19 JouleThe eye requires 20 photons per sec = 6.6214 x 10-18 watt.The ratio of the required power to the power of the source is the ratio of the area of a 7mm circleto the area of the big sphere centered on the source.(6.6214 x 10-18) / (100) = (pi x 0.00352) / (4 pi R2)R2 = (100) (pi x 0.00352) / (4 pi x 6.6214 x 10-18)R = (5 x 0.0035) / (sqrt(6.6214) x 10-9)= 0.0068 x 109 = 6.8 x 106 meters= 6,800 km (4,225.8 miles)Wow !

7mm is thicker
9mm
.5mm is finer than .7 mm
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.
Yes, by 2 mm (.07in).
It is 7 mm - 2 mm = 5 mm.
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).
7 mm is about the width of a standard #2 pencil.
Depend on the temperature of the water. >80F none 65-79F use 5mm <65 use 7mm
These are discontinued along with the .5mm black. The .7mm yellow have been upgraded to a refillable model widely available at amazon, staples, etc.But http:/www.cspoutdoors.com still has some of the discontinued pencils. Good luck.
7mm is about the thickness of a standard yellow pencil. In inches, 7 mm is about 0.28 inches.
