MM is a measurement in the metric system. Caliber is a measurement in inches.
11.43 millimeters
They're both measurements of the diameter of the round (or the barrel). Caliber is a measurement in inches, and millimeters are millimeters. For instance, a .30 caliber bullet is 30 hundredths of an inch, or 7.62 millimeters in diameter.
9
It's a .30 caliber bullet. .30 caliber is the American designation for the size, 7.62 millimeters is the European designation.
If you mean how long is the cartridge for an AK47, it's 39 millimeters long. The caliber 7.62x39mm.
Pretty difficult to have any milliliters in a caliber since milliliters measure volume and caliber is a measure of length and width. I think we have a typo. here. If I understand the question correctly calibers are measured two ways, either millimeters or thousandths of an inch. There are approx. 25.4 millimeters (m/m) in 1.000 inch
The AK-47 assault rifle is chambered for the 7.62x39mm round, which is of the 7.62 millimeter caliber.
Caliber refers to the diameter of the bullet the gun fires. The caliber of a 9mm is 9 millimeters. That is about .356 inches.
Size and relative power. A .40 caliber bullet is .40 of an inch and the entire cartridge is 28.8 millimeters long. A .50 caliber (handgun) bullet is .50 of an inch and the entire cartridge is 40.99 millimeters long. The .50 caliber has more powder, more velocity, and more muzzle energy.
They are different ways of expressing the same thing. A bullet that is 7.65mm is just that- 7.65 millimeters in diameter. Is the US, we frequently use caliber rather than millimeters- that same bullet was be a .32 caliber- or 32/100ths of an inch in diameter.
`Caliber` is a standard of measure in thousandths of an inch. For example, a .30 caliber bullet would measure 300 thousandths of an inch diameter, or three tenths of an inch. 1 caliber would be 1000 thousandths or 1 inch which equals 25.4 mm.
