If you mean are there other units of measure for firearm bore sizes, the answer is yes.
The two most common methods of stating the bore diameter of a firearm are "caliber" and "gauge".
Calibers can be expressed in decimals of an inch (examples: .357, .308, .45) or in millimeters (examples: 9 mm, 7.62 mm, 5.56 mm) as measured inside the bore. Rifles and handguns are normally listed by caliber.
Gauges are a more dificult to understand. If you make a lead ball the same diameter as the inner bore diameter and figure out how many of the lead balls it would take to make 1 pound, that is your gauge number. Thus a 12 gauge means it would take 12 lead balls to equal 1 pound whereas the smaller diameter 20 gauge would take 20 balls to equal a pound. Shotguns are normally listed by gauge.
You can convert gauges to calibers if you want. For eaxmple a 12 gauge is roughly .72 inch caliber.

The short answer is no. The longer answer is, you might be able to get a .40 caliber cartridge to fire from a .45 caliber gun, but it may damage the gun, and even if it doesn't damage the gun, it will cause other problems. In general (with only a few exceptions) you should never try to fire any cartridge in any gun other than a gun designed for that caliber.
