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.
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 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.
You look up the definition of a "barrel", for example the Wikipedia article on "barrel (unit)", decide which definition you want to use (there are several), check how many liters your chosen "barrel" has, then divide the 12 liters by this number.
A half barrel is normally indicating a wine barrel, as opposed to a crude oil barrel. Europe, including the UK had multiple measurement systems but this one was standard throughout, for wine and beer. (beer volumes are now measured differently) A wine barrel is 31.5 wine gallons, equal to the US standard gallon (this is where the US standard came from). A gallon in this measurement system is 128 fluid ounces. A half barrel is 15 3/4 gallons. 15.75 x 128 = 2016 fl.oz. By water weight this fluid ounce is 29.6 grams, an ounce weight is 28.35 grams so by weight this 2016 fl.oz. would be 2104 and 7/8 ounces(or imperial fl. oz.). An imperial barrel is 26 imperial gallons or 4160 ounces; a half barrel imperial is thus 2080 fl.oz. imperial. A 50 liter keg on the other hand is equal to 1763.67 imperial fluid ounces, a keg usually refers to a half barrel in most systems, in the US system this would be 1689.2 fl. oz.
Millilitre is a unit of volume not for mass.An UK beer barrel has 160 L.Because 1 L has 1 000 mL, 1 barrel has 160 000 mL.For a common beer density of 1,01 g/mL the mass is approx. 162 kg.
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.
Use a density factor to make a barrel to ton conversion. The ton is a metric weight and the barrel is a volume measurement.
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.
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
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.
Barrel 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.
Caliber is the size of the barrel's inside diameter, in fractions of an inch. A .25 caliber pistol fires a bullet that is about 0.25 inches across. Pistol can range from very small (about 10 caliber) up to very large (75 caliber) and there are hundreds of different cartridge sizes in between.
