The question, as stated, cannot be answered sensibly. A gallon is a measure of volume, with dimensions [L3]. An inch is a measure of distance, with dimensions [L]. The two measure different things and elementary dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
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.
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.
To convert barrels per day (bbld) to metric tons per annum (mtpa), you need to know the density of the substance being measured. Once you know the density, you can use the formula: mtpa = bbld * 0.1364 * density (in metric tons per cubic meter). This conversion takes into account the volume of a barrel (0.1364 cubic meters) and the density to convert the measurement from volume to weight.
It depends on the substance being measured in the barrel. A typical oil barrel (bbl) is equivalent to about 136 kilograms. However, for other liquids or solids, the conversion may vary.
To convert 4 million metric tons to barrels per day, you need to know the specific gravity or density of the substance being measured. The conversion ratio will vary depending on the substance.

The diameter of a rifle's bore is measured in either inches or millimeters, depending on the measurement system used. In the United States, it is typically expressed in inches (for example, .223 caliber), while many other countries use millimeters (such as 7.62 mm). This measurement indicates the internal diameter of the rifle's barrel and is crucial for determining the appropriate ammunition that can be used.
The inside diameter of the barrel measured between the lands.
A barrel is not a uniform unit of measurement. Therefore, the two units are incompatible.
A rifle bore is measured by determining its diameter, typically expressed in inches or millimeters. The measurement is taken from land to land, which refers to the raised portions of the rifling inside the barrel, rather than from groove to groove. For example, a .30 caliber rifle has a bore diameter of approximately 0.308 inches. This measurement is crucial for ensuring that the correct ammunition is used for optimal performance and safety.
The outside dimension of a barrel is simply the diameter. The traditional inside measurement of a rifled barrel is caliber and the traditional inside measurement of a smoothbore (shotgun) barrel is gauge. Strictly speaking, smoothbore gauges are not diameters. Gauge number is the number of round balls fitting the bore that can be made from a pound of lead.
Use a density factor to make a barrel to ton conversion. The ton is a metric weight and the barrel is a volume measurement.
A 243 calibre rifle is Just that. The bore (internal measurement of the barrel) is 0.243 of an inch in diameter.
Simple, it it is a true barrel simple find the measurement from inside to inside of your barrel and divide by 2. IF it is not a perfect half circl barrel or true barrel, simple find your chord (measurement inside to inside) and find your rise. Once you have these measurements you can use your diameter formula to figure the radius
The diameter
Barrel diameter
It is the measurement of the bore size. The gauge is the number of balls the diameter of the barrel that could be made from a pound lead. So a lead ball weighing 1 1/3 ounces will fit in the barrel of a 12 gauge shotgun (12 * 1 1/3 = 16 ounces), a 1-ounce ball would fit a 16 gauge barrel, and one that weighs 4/5 ounce will fit a 20 gauge. The exception is the .410 which is the actual measurement of the barrel diameter, 41/100 inch.
