Draft Beer Calculations & Conversions

Quick-reference conversions and facts for draft beer professionals, bar owners, brewers, and enthusiasts — PSI to Bar, ounces to pints, serving temperatures, and food pairing, all in one place.

Quick-reference conversions

Not every beer calculation needs a full-blown draft system calculator. Sometimes you just need to convert PSI to bar for imported equipment, figure out how many ounces are in a growler, or check what food pairs with a Belgian Tripel. This page rounds up the everyday conversions and reference facts in one place, so you don't need to bookmark six separate pages.

Reference

PSI ↔ Bar ↔ kPa

1 PSI = 0.0689 Bar = 6.895 kPa. Most draft beer runs 10–14 PSI (0.69–0.97 Bar). European/imported regulators are usually marked in Bar; European draft systems commonly serve at 0.8–1.0 Bar. To convert PSI to Bar, multiply by 0.0689. To convert Bar to PSI, multiply by 14.5.

Ounces, Pints & Kegs

1 pint = 16 fl oz. 1 quart = 32 fl oz. 1 gallon = 128 fl oz = 8 pints. A half-barrel keg (15.5 gal) pours 124 16-oz pints or 165 12-oz servings. A sixtel (5.16 gal) pours 41 pints or 55 12-oz servings.

Beer Serving Temperatures

Lagers and light beers: 38–45°F. Pale ales and IPAs: 45–50°F. Stouts, porters, and Belgian ales: 50–55°F. To convert Fahrenheit to Celsius: (°F − 32) × 5/9. Most draft systems and kegerators should hold 36–38°F at the tap.

Beer & Food Pairing

IPAs cut through spicy and fatty food; stouts pair with chocolate, oysters, and smoked meats; Belgian Tripels go with mussels, roast pork, and aged Gouda; wheat beers pair with salads and light seafood.

Frequently Asked Questions

What PSI should I set my CO2 regulator to for draft beer?
Most draft beers at 36–38°F need 10–14 PSI of pure CO2. Use the carbonation calculator on our tools page for your exact beer style and temperature. For imported equipment that uses Bar instead of PSI, multiply PSI by 0.0689 to get Bar — 12 PSI equals approximately 0.83 Bar.
How many pints are in a standard keg?
A half-barrel keg (1/2 BBL, 15.5 gallons) holds 124 16-oz pints or 165 12-oz servings. A sixtel keg (1/6 BBL, 5.16 gallons) holds 41 pints or 55 12-oz servings. For any other vessel size, divide the total ounces by 16 for 16-oz pints, or by 12 for 12-oz servings.
What temperature should I serve IPA?
IPAs are best served at 45–50°F (7–10°C), sometimes called "cellar temperature." At this range, hop aromatics are more pronounced than at colder serving temperatures. Over-chilling an IPA mutes the hop character significantly.
What food goes best with a Belgian Tripel?
Belgian Tripels pair beautifully with steamed mussels, roast pork, scallops, aged Gouda, and spiced chicken. The high carbonation and fruity esters cut through rich creamy sauces.
How do I convert Fahrenheit to Celsius for beer serving temps?
Subtract 32, then multiply by 5/9. For example, 38°F is (38 − 32) × 5/9 = 3.3°C. Most kegerators and draft systems should hold 36–38°F (2–3°C) at the tap.
