MM is a measurement in the metric system. Caliber is a measurement in inches.
A .45 caliber bullet typically measures 11.43 millimeters in diameter.
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.
A .38 caliber bullet typically has a diameter of approximately 9.1 millimeters. The designation ".38 caliber" refers to the bullet's diameter, which is often rounded to the nearest hundredth of an inch. Therefore, a .38 caliber bullet can be generally considered to be around 9 mm in metric measurements.

It's a .30 caliber bullet. .30 caliber is the American designation for the size, 7.62 millimeters is the European designation.
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
If you mean how long is the cartridge for an AK47, it's 39 millimeters long. The caliber 7.62x39mm.
Caliber refers to the diameter of the bullet the gun fires. The caliber of a 9mm is 9 millimeters. That is about .356 inches.
Probably, but it is simple enough that anyone can do the math without much trouble. Keep in mind that the only difference is the measurement system used (inches versus millimeters). One inch equals 25.4 millimeters. So, take the number of millimeters and divide by 25.4 (the number of millimeters in an inch). That's all. To convert back to millimeters, just multiply by 25.4.
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.
Caliber is measured by the diameter of the interior of a firearm's barrel, typically expressed in inches or millimeters. For example, a .45 caliber firearm has a barrel diameter of 0.45 inches, while a 9mm caliber firearm has a barrel diameter of 9 millimeters. This measurement helps identify the size of the ammunition that can be used with the firearm.
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.
