Convert between beer serving sizes including standard bottles, tallboy cans, pints, growlers, and kegs. Supports both US and UK pint measurements for homebrewing and party planning.
| Container | fl oz | mL | Liters | US Gallons | Standard Bottles |
|---|---|---|---|---|---|
| Standard bottle | 12 | 355 | 0.355 | 0.094 | 1 |
| Tallboy can | 16 | 473 | 0.473 | 0.125 | 1.33 |
| UK pint | 19.2 | 568 | 0.568 | 0.150 | 1.60 |
| Bomber | 22 | 651 | 0.651 | 0.172 | 1.83 |
| 40 oz bottle | 40 | 1,183 | 1.183 | 0.313 | 3.33 |
| Growler | 64 | 1,893 | 1.893 | 0.500 | 5.33 |
| Mini keg | 169 | 5,000 | 5.0 | 1.32 | 14.1 |
| Sixtel keg | 661 | 19,550 | 19.55 | 5.16 | 55.1 |
| Quarter barrel | 992 | 29,337 | 29.34 | 7.75 | 82.7 |
| Half barrel (full keg) | 1,984 | 58,674 | 58.67 | 15.50 | 165.3 |
Beer volume conversion is the process of translating between different beer container sizes and measurement units. Beer comes in a wide variety of serving sizes, from small tasting glasses to 15.5-gallon kegs, and being able to convert between these sizes is essential for party planning, homebrewing, and comparing prices.
The confusion often arises from the variety of container sizes and the difference between US and UK measurements. A US pint is 16 fluid ounces while a UK pint is 20 fluid ounces — a 25% difference that can significantly affect calculations for international recipes or pub orders.
Homebrewers frequently need to convert between metric and imperial measurements, calculate how many bottles a batch will fill, or determine the right keg size for their setup. Event planners need to estimate how many kegs or cases to order for different group sizes.
How many standard bottles in a sixtel keg? A sixtel holds 19,550 mL and a standard bottle is 355 mL. So: 19,550 ÷ 355 = 55.1 bottles. You can fill about 55 twelve-ounce bottles from one sixtel keg.
How many US pints in a growler? A growler is 1,893 mL and a US pint is 473 mL. So: 1,893 ÷ 473 = 4.0 pints. A growler holds exactly 4 US pints (or 3.33 UK pints).
You need 200 pints for a party. How many full kegs? 200 pints × 473 mL = 94,600 mL. A half barrel is 58,674 mL. So: 94,600 ÷ 58,674 = 1.61 kegs. You need 2 full kegs (with some left over).
A full keg is about 165 bottles. A sixtel is about a third of that (55). A growler is about 5.3 bottles or 4 pints. Remember: UK pints are 25% bigger than US pints.
| Keg Type | Gallons | 12 oz Servings | 16 oz Pints | Best For |
|---|---|---|---|---|
| Mini keg | 1.32 | 14 | 10 | Personal use, gifts |
| Cornelius (homebrew) | 5.0 | 53 | 40 | Homebrewing |
| Sixtel (1/6 barrel) | 5.16 | 55 | 41 | Home kegerator, small events |
| Quarter barrel | 7.75 | 83 | 62 | Medium parties |
| Slim quarter | 7.75 | 83 | 62 | Narrow kegerators |
| Half barrel (full keg) | 15.5 | 165 | 124 | Bars, large events |
Knowing how many servings each container holds prevents running out or over-ordering for events, saving money and reducing waste.
Homebrewers need precise volume calculations for recipes, yeast pitching rates, and determining how many bottles a batch will fill.
Converting to a common unit (like price per ounce) lets you compare value across bottles, cans, growlers, and kegs accurately.
European beers come in 330 mL and 500 mL bottles. Converting to familiar US ounces or pints helps you understand what you are getting.
A UK pint is 20% larger than a US pint. If following a British recipe or ordering in a British pub, account for this difference.
Kegs come in many sizes. A sixtel is only a third of a full keg. Always confirm the keg size before calculating servings.
When pouring from a keg, expect about 10-15% loss from foam and the last bit that cannot be poured. Plan accordingly.
European bottles are typically 330 mL (11.2 oz) or 500 mL (16.9 oz), not the US standard 355 mL (12 oz).
A standard full-size keg (half barrel) holds 15.5 US gallons or 58.67 liters, which equals approximately 165 standard 12-ounce bottles or 124 pints (16 oz). A sixtel keg holds about 55 bottles, and a quarter barrel holds about 83 bottles.
A US pint is 16 fluid ounces (473 mL), while a UK pint is 20 fluid ounces (568 mL). A UK pint is about 20% larger than a US pint. This is important when following British recipes or ordering beer in the UK versus the US.
A standard US beer bottle contains 12 fluid ounces (355 mL). Other common sizes include the tallboy can at 16 oz (473 mL), the bomber at 22 oz (651 mL), and the 40 oz bottle (1,183 mL).
A growler is a 64 fluid ounce (1.89 liter) glass jug used to transport draft beer from a brewery or taproom. Half growlers (32 oz) and crowlers (32 oz cans) are also common. A full growler equals about 5.3 standard 12-oz bottles.
A half barrel (full-size) keg contains 15.5 US gallons or 58.67 liters. It is the standard keg size used in most commercial bars and restaurants. Other keg sizes include the quarter barrel (7.75 gal) and sixtel (5.16 gal).
A general rule is 2 drinks per person for the first hour and 1 drink per hour after that. For a 4-hour party with 20 guests, plan for about 100 beers (roughly 8.5 cases or two sixtel kegs). Use our Party Drink Calculator for more precise planning.
A sixtel (also called a sixth barrel) holds 5.16 gallons (about 55 twelve-ounce bottles), while a quarter barrel holds 7.75 gallons (about 83 bottles). Sixtels are slimmer and fit in most home kegerators, making them popular for home use.
Divide the milliliters by 29.5735 to get US fluid ounces. For example, a 330 mL European bottle divided by 29.5735 equals 11.16 fluid ounces, slightly smaller than a standard US 12 oz bottle.
A bomber is a 22-ounce (650 mL) beer bottle, commonly used for craft beers and specialty brews. It holds about 1.83 standard bottles worth of beer. Bombers have become less common in recent years as the craft beer industry has shifted toward 16 oz cans.
A standard full-size keg (half barrel) contains 58.67 liters. A quarter barrel contains 29.34 liters, and a sixtel contains 19.55 liters. European kegs vary but commonly hold 50 liters (the DIN keg standard).
