38 mm = 3.8 cm
38 millimeters is 1.5 inches or 0.12ft
Diameter: 2 times 19 = 38 mm
38 mm ÷ 25.4 mm/in ≈ 1½"Direct Conversion Formula38mm*1 in25.4 mm=1.496062992in
If you mean the 9 mm Parabellum AKA 9x19 mm or 9 mm "Luger", the .38 Special is physically larger. The case length of the .38 is 0.401 inches longer. The over all loaded cartidge length of the .38 is 0.381 inches longer. Case diameter is nearly identical between the two, but the .38 has a larger rim/case head by 0.046 inches. The 9 mm fires a 0.355 inch diameter bullet whereas the .38 fires a 0.357 inch diameter bullet.
38 millimeters = about 1.5 inches. (1.49606299 inches)
i think that you do math?
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]
To convert millimeters to inches, you can use the conversion factor where 1 inch is equal to 25.4 millimeters. Therefore, to convert 38 mm to inches, you divide 38 by 25.4, which equals approximately 1.5 inches. So, a diameter of 38 mm is about 1.5 inches.
The diameter would be 100 mm, which is equivalent to 10 cm.
You would use millimetres.
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]
