About this calculator
This calculator determines dissolved CO₂ in volumes — the standard brewing unit where 1 volume means 1 litre of CO₂ gas (at standard conditions) dissolved per litre of liquid — from the liquid temperature and the head pressure applied above it, using the solubility relationship behind classic force-carbonation charts. Colder liquid holds more dissolved gas at any given pressure, which is why brewers chill beer before force-carbonating it.
Most American lagers sit around 2.5–2.8 volumes, British ales closer to 1.5–2.0, and Belgian styles or sodas can run 3.0–4.5 volumes or higher. Homebrewers and beverage producers use this figure to dial in a keg's regulator pressure at a known fridge temperature to hit the exact carbonation level a style calls for.
