How Many Milliliters in a 12 Oz Can?

A 12 oz can holds 354.9 milliliters — 355 mL on the label. Multiply fluid ounces by 29.5735: 12 × 29.5735 = 354.88 mL. That is the US fluid ounce, and a 12 oz can of soda, beer, or energy drink all hold the same volume. Convert any can size instantly with our free fluid ounces to milliliters converter.

The Short Answer: 354.9 Milliliters

A standard 12 oz can contains 354.88 milliliters, which rounds to 354.9 mL and is printed as 355 mL on the label. The math is one multiplication: one US fluid ounce equals 29.5735 milliliters, so 12 × 29.5735 = 354.882 mL. That single number answers the question for every drink that comes in a 12 oz can, because the can's volume does not depend on what is inside it. Soda, beer, sparkling water, and energy drinks all use the same 12 oz shell, so they all hold 354.9 mL. The label rounds to 355 mL because food and drink labels round to the nearest whole milliliter, and the 0.12 mL difference is far smaller than the tolerance of any filling line. If you only need the number for a recipe, a conversion, or a label check, 355 mL is the figure to use. For exact work, our fluid ounces to liters converter gives the same answer in liters: 0.3549 L.

The Formula: Ounces to Milliliters

The conversion rests on one exact factor: 1 US fluid ounce = 29.5735295625 milliliters, usually shortened to 29.5735. The formula is milliliters = fluid ounces × 29.5735, and it works for any can, bottle, or jug. For a 12 oz can: 12 × 29.5735 = 354.882 mL. For an 8 oz can: 8 × 29.5735 = 236.588 mL. For a 16 oz tallboy: 16 × 29.5735 = 473.176 mL. The reverse trip divides instead of multiplying: fluid ounces = milliliters ÷ 29.5735, so 355 ÷ 29.5735 = 12.004 oz, which confirms the round trip lands back on 12. A mental shortcut helps when no calculator is handy: one fluid ounce is very close to 30 mL, so 12 oz is roughly 360 mL. That estimate is about 1.4 percent high, close enough for a rough guess but not for a recipe or a label. For the reverse direction in detail, our guide to converting milliliters to ounces walks through the same factor from the other side.

US vs Imperial Fluid Ounces: The 341 mL Trap

The 354.9 mL answer assumes US fluid ounces, and the imperial fluid ounce used in the United Kingdom is a different, larger unit: one imperial fluid ounce equals 28.4131 milliliters. Twelve imperial fluid ounces therefore equal 340.96 mL, about 14 mL less than the US figure, a gap of roughly 4 percent. The two ounces exist because the US and the UK defined their fluid ounces from different gallons: the US gallon is 3.78541 liters divided into 128 ounces, while the imperial gallon is 4.54609 liters divided into 160 ounces. In practice the trap rarely bites on cans, because British cans are not sold as 12 oz at all — the standard UK can is 330 mL — but it does bite on recipes, old cookbooks, and product labels from the imperial era. If a source says 12 oz and the answer it implies is near 341 mL, it is using imperial ounces; if the answer is near 355 mL, it is using US ounces. For drinks sold in the United States, which is where the 12 oz can is the standard, always use 29.5735 and 354.9 mL.

How Many Milliliters in a 12 Oz Can of Soda, Beer, and Energy Drinks

The drink inside the can changes nothing about the volume. A 12 oz can of soda holds 354.9 mL, a 12 oz can of beer holds 354.9 mL, and a 12 oz can of energy drink holds 354.9 mL, because all three are filled into the same standard can. What changes is only the label: soda cans usually print 12 FL OZ (355 mL), beer cans print the same, and energy drinks in the 12 oz size do too, though many energy drinks use smaller 8.4 oz cans instead. Carbonation does not change the volume either. A carbonated drink contains dissolved gas, but the liquid volume in the can is still 354.9 mL; the fizz is gas dissolved in the liquid and in the small headspace at the top, not extra liquid. One detail worth knowing: the can's nominal capacity is slightly larger than its fill volume, because the fill leaves a small headspace for expansion, so the can itself could hold a few milliliters more than 354.9 mL if filled to the brim. The printed number is the fill, not the brim capacity, and it is the fill that matters for recipes, nutrition labels, and serving sizes.

Every Standard Can Size in Milliliters

The 12 oz can is the standard, but it sits in a family of sizes, and the same × 29.5735 factor converts all of them. A 7.5 oz mini can holds 221.8 mL. An 8 oz can holds 236.6 mL. The 8.4 oz slim can used by many energy drinks holds 248.4 mL. The standard 12 oz can holds 354.9 mL. A 16 oz tallboy or pint can holds 473.2 mL. A 19.2 oz stovepipe can holds 567.9 mL. A 24 oz large can holds 709.8 mL. Two anchors make the whole table derivable from memory: 8 oz is about 237 mL, just under a quarter liter, and 16 oz is about 473 mL, just under half a liter. From those, doubling and halving reach everything else: half of 473 is 237 (our 8 oz), and 12 oz sits exactly halfway between 8 and 16, which is why 354.9 mL is the midpoint of 236.6 and 473.2. For kitchen-scale conversions in the same family, our guide to converting cups to milliliters covers the cup side of the same math.

12 Oz Cans Around the World: 330 mL, 350 mL, 375 mL

Outside the United States, the 12 oz can mostly does not exist, and the standard cans are metric sizes that look confusingly close to it. The European Union and the United Kingdom use a 330 mL can, which equals 11.16 US fluid ounces — about 25 mL less than an American 12 oz can. Japan uses a 350 mL can, which equals 11.83 oz, only about 5 mL short of the US size. Australia uses a 375 mL can, which equals 12.68 oz, about 20 mL more than the US can. The practical consequence is that a recipe, a serving-size comparison, or a product review that mentions a can without saying where it was bought may be talking about any of these four sizes. A European recipe calling for one can of soda means 330 mL, not 355 mL, and substituting an American can adds about 7 percent more liquid. An Australian can adds about 6 percent. The reverse matters for travelers too: an American drinking a 330 mL can abroad is getting about 0.84 oz less than the can at home. When a label gives milliliters only, divide by 29.5735 to get US ounces and you will know immediately which standard you are holding.

How Many 12 Oz Cans in a 2 Liter Bottle?

A 2 liter bottle holds 2,000 mL, and dividing by the can's 354.88 mL gives 5.64 cans, so call it five and a half 12 oz cans per 2 liter bottle, with a little left over. One liter holds 1,000 ÷ 354.88 = 2.82 cans, so a liter bottle is just under three cans. Going the other direction, six 12 oz cans total 2,129.3 mL, slightly more than a 2 liter bottle, which is why a six-pack of cans holds more soda than the big bottle on the shelf next to it. These equivalents are handy for parties and recipes: a punch recipe calling for two liters of soda needs six cans, not five, and a recipe calling for three cans needs about 1.06 liters. The bottle-versus-can comparison, including price per ounce and how fast each goes flat, is covered in our guide to how many ounces are in a 2 liter bottle of soda, and the half-gallon jug size is broken down in our 64 oz in liters guide.

People Also Ask: Is 12 Oz 250 mL, 500 mL, or 200 mL?

Three round numbers get confused with 12 oz, and all three are wrong. 250 mL is not 12 oz: 250 ÷ 29.5735 = 8.45 oz, so a 250 mL can is a small 8.45 oz serving, the size of many European energy drinks. 500 mL is not 12 oz: 500 ÷ 29.5735 = 16.91 oz, so a 500 mL bottle is a 16.9 oz bottle, nearly half a liter and a full 40 percent larger than a 12 oz can. 200 mL is not 12 oz: 200 ÷ 29.5735 = 6.76 oz, a small juice-box size. The confusion comes from the metric sizes that dominate outside the US: 250 mL and 500 mL are standard European bottle sizes, and people map them onto the familiar American 12 oz can by feel. The check that settles any of these is the same division: milliliters ÷ 29.5735 gives US ounces, and only 354.9 mL lands on 12. If a can's label reads 330 mL, 350 mL, or 375 mL, it is a metric can, not a 12 oz can, and the section above gives its exact ounce equivalent.

How to Read a Can Label and Check the Math

Every can sold in the US prints both units, usually as 12 FL OZ (355 mL), and that pair is itself a check: if the milliliters divided by the ounces is near 29.57, the label is consistent. A label reading 12 FL OZ (341 mL) would be an imperial-ounce label, and a label reading 12 FL OZ (330 mL) would be a metric can mislabeled in ounces. One more trap to watch for is fluid ounces versus weight ounces. Fluid ounces measure volume, while ounces on a scale measure weight, and they only coincide for water. Twelve fluid ounces of water weighs about 12.5 avoirdupois ounces, because 354.9 grams divided by 28.35 grams per ounce is 12.52 oz, so a can of water is heavier in ounces than its fluid-ounce count suggests. For soda the gap is similar, since soda is mostly water with dissolved sugar. The rule is simple: FL OZ on a drink label always means volume, and the milliliter figure next to it is the number to trust.
