Method and sourcefl oz to ml Conversion Formula
To convert US fluid ounces to millilitres, multiply the fl oz value by 29.5735. This converts US customary fluid ounces (1/128 of a US gallon). The imperial fluid ounce used in older Australian and British recipes is slightly smaller at 28.4131 ml each.
Fluid Ounces and Milliliters Explained
Fluid Ounces (fl oz)
The US fluid ounce (fl oz) is 1/128 of a US gallon, equal to exactly 29.5735 millilitres. Despite the name, it measures volume, not weight — it's the liquid counterpart of the weight ounce. American recipes, nutrition labels, bar menus and cosmetics bottles all quote fluid ounces: 8 fl oz make a US cup, 16 fl oz a US pint, and 128 fl oz a gallon.
Where it is used: Standard liquid measure in the United States for food labels, recipes, drinks and personal-care products; Australian shoppers mainly see it on US imports, while older Australian and British recipes use the different 28.4131 ml imperial version.
Origin: Traces back to the English fluid ounce defined as the volume of one ounce of water; the US fixed it as 1/128 of the 231-cubic-inch gallon in the 19th century. Britain and Australia kept the imperial version until switching to metric.
Milliliters (ml)
The millilitre (ml) is one-thousandth of a litre — identical to a cubic centimetre — and Australia's working unit for small liquid volumes. Kitchen jugs, medicine syringes, perfume vials and lab pipettes are all graduated in millilitres. At this scale the unit matches everyday intuition: a teaspoon is 5 ml, a standard pub nip is 30 ml, and a flat white starts around 160 ml.
Where it is used: Universal in Australia for recipes, pharmaceuticals, cosmetics and beverage labelling; also the base unit on scientific glassware worldwide.
Origin: A decimal subdivision of the French Revolutionary litre; its identity with the cubic centimetre made it indispensable to chemistry and medicine — and Australia adopted it with the rest of the metric system in the 1970s.

When You Need Fluid Ounces to Milliliters Conversions
Baking from American blogs
US baking recipes measure milk, oil and buttermilk in fl oz, while your metric jug and Australian recipe books work in millilitres. Converting on the spot — 4 fl oz of oil is 118.29 ml, 6 fl oz of milk is 177.44 ml — keeps cake batters hydrated exactly as the recipe author intended.
Comparing skincare sizes
Serums and toners list 1 fl oz, 1.7 fl oz or 3.4 fl oz on US storefronts, while the same products at Australian retailers show 30 ml, 50 ml or 100 ml. Converting 1.7 fl oz to 50.27 ml lets you run honest price-per-millilitre comparisons before you checkout.
Preparing baby formula
Australian formula tins and day care centres work in ml, but US-imported feeding charts are written in fl oz. A 4 fl oz bottle is 118.29 ml and a 6 fl oz bottle is 177.44 ml — converting the schedule once keeps parents, grandparents and educators mixing identical feeds.
Reading beverage nutrition panels
US drink labels define a serving as 8 fl oz or 12 fl oz, while Australian bottles and cans state 250 ml, 330 ml or 375 ml. Knowing 8 fl oz = 236.59 ml and 12 fl oz = 354.88 ml tells you whether that "one serving" of juice or energy drink is actually the whole can.

About Fluid Ounces to Millilitres Converter
Our free online fluid ounces to millilitres converter gives instant, accurate volume conversions for Australians juggling American measures with our fully metric kitchens. Australia went metric decades ago, but fluid ounces still turn up everywhere: US recipe blogs, American skincare and supplement imports, fitness shaker charts and bar menus. The millilitre rules Australian measuring jugs, pharmacy syringes and every label at Coles and Woolworths. This converter applies the exact US customary definition of 29.5735 ml per fluid ounce and clearly separates it from the 28.4131 ml imperial fluid ounce found in older Australian and British recipes, so whether you're baking from an American blog, comparing skincare sizes or preparing formula, your volumes come out spot on every time.
Expert Tips for fl oz to ml Conversion
Memorise the kitchen anchors: 1 fl oz = 29.57 ml, 8 fl oz = 236.59 ml (1 US cup), and 16 fl oz = 473.18 ml (1 US pint). Nearly every American recipe reduces to these three.
US nutrition panels round generously — a "12 fl oz (355 ml)" serving is exactly 354.88 ml. Don't chase that 0.12 ml; it disappears in the pour.
Skincare pricing is easier in ml: a 1 fl oz serum is 29.57 ml, so a 1.7 fl oz bottle holds 50.27 ml and can be compared price-per-millilitre against the 50 ml bottles at Chemist Warehouse or Mecca.
When a recipe mixes systems (butter in grams, milk in fl oz), convert the liquids to ml first, then weigh everything on your kitchen scales — millilitres and grams lock together neatly for water-like liquids.
Bartending at home: a US jigger is 1.5 fl oz (44.36 ml), but an Australian standard nip is 30 ml. Convert the cocktail recipe first, then decide whether to pour US-style or keep to the Aussie nip.
