What is a gun measured in?

Answer 1

Bullets are primarily measured by the diameter (caliber) and their weight.

Calibers can be expressed in hundredths or thousandths of an inch or in millimeters -- typical small arms calibers range between .17 to .50 inch caliber or about 4.4 to 12.7 mm caliber.

Weight is expressed in grains or grams. There are 7000 grains to a pound. bullet weights for small arms can range from as low as 20 grains to over 800 grains.

Answer 2

Caliber is simply the diameter of the bullet in the cartridge. It can be expressed in hundredths or thousandths of an inch, such as .40 or .45, or it can be expressed in millimeters, such as 9mm or 10mm. As far as actually physically measuring it, the bullet's diameter can be measured with a caliber gauge.

Answer 3

This question is extremely vague and poorly worded. I'm assuming you meant to ask, "How do you measure the chambering of a gun?" That means how do you figure out what sort of ammunition goes into the gun.

Ammunition can be measured in two ways. There's a millimeter system and caliber system. Example: A large portion of modern pistols are chambered in 9mm.

Example: This rifle takes 7.62x51mm. ammunition. That means the barrel is .30 and the shell casing is 51 mm long.

Note on the above example ".30" is generally pronounced "thirty-caliber."

Answer 4

Guns are typically measured in caliber, which refers to the diameter of the gun barrel. Caliber is usually expressed in millimeters or inches. Additionally, guns may also be measured by length, weight, capacity, and various other specifications depending on the type of gun.

Answer 5

It depends on the bullet. A 7.62 round is 7.62 mm in diameter, and a 303 is 0.303 inch in diameter and a 22 bullet is 0.22 inch diameter.

Answer 6

Bullets are measured by their diameter; either in millimeters or hundredths or thousandths of an inch. For Example: A 5.56mm bullet is the same diameter as a .223" bullet.

Answer 7

Usually in Feet per second, or FPS. If you do the math right, you can convert it into M.P.H. 1000 FPS = 681.1 M.P.H
