Both no 380/9 = 42.2222 380/3 = 126.6666
9 mm * 9 mm = 81 mm2 = 0.81 cm2
1 mm is the thickness of a dime. 1cm is 10 mm
1 cm = 10 mm 2 cm = 20 mm 3 cm = 30 mm . . 9 cm = 90 mm That's more than 77 mm.
It is a length of 45 mm.
Yes. .38 special is a revolver cartridge and .380 is an auto cartridge. Also, the .38 will almost always have a heavier bullet and more muzzle energy than a .380. The .38 bullet is 0.357 inches in diameter while the .380 is 0.355 inches in diameter. Technically, the .380 cartridge is considered part of the 9 mm class of bullets. [9 mm x 19 mm = 9 mm Luger or 9 mm Parabellum, 9 mm x 18 mm = 9 mm Tokarov, and 9 mm x 17 mm = .380 ACP]
It depends on the bullet weights. The 9 mm (AKA 9x19 mm, 9 mm Luger, or 9 mm Parabellum) is faster than the .380 ACP (AKA 9 mm Kurz) except when you compare the lightest .380 bullets to the heaviest 9 mm bullets. If you compare the same bullet weights in each, the 9 mm is always faster.
Yes they is a differnent. When people say "38" they usually mean .38 special, which is a revolver cartridge. .380 ACP is a semi-automatic cartridge. The bullet in a .380 cartridge, even though it's called .380, is actually very slightly smaller in diameter, and lighter than the bullet in a .38 cartridge. The .38 bullet is 0.357 inches in diameter while the .380 is 0.350 inches in diameter. Technically, the .380 cartridge is considered part of the 9 mm class of bullets. [9 mm x 19 mm = 9 mm Luger or 9 mm Parabellum, 9 mm x 18 mm = 9 mm Tokarov, and 9 mm x 17 mm = .380 ACP]
You can from some, but they have to be designed to shoot both.
The .380 automatic cannot shoot 9mm Parabellum ammo.
9mm Luger.

Nothing, reallyThe main difference is that the term ".38 caliber" usually refers to revolvers while ".380 ACP" refers to automatic handguns. The two cartridges have different lengths, diameters, rims, and bulet weights. They do NOT interchange.
I have seen it done. It will fail to eject or fail to fire. Don't have a box of .380 present while shooting 9mm.
No. Generally speaking, you can only use the correct caliber magazine for any given handgun, and .380 and 9mm are not interchangeable.
Some revolvers will take .357, .38 and 9 mm. Whether or not a particular revolver will or not is a different issue. One police department went to them and went to .45 the next year. They may not have worked very well.
While the .380 is sometimes called the 9mm Kurz, it is not the same as the 9mm parabellum (also called 9mm Luger and 9x19). It is shorter than the 9mm.
