Quick reference

How to convert fl oz to ml

The conversion formula is ml = fl oz × 29.5735. US fluid ounces are volume: multiply by 29.5735. In the UK an imperial fluid ounce is 28.413 ml — about 4% smaller. (Weight ounces to grams live on the grams-to-ounces page.)

Going the other way? See the milliliters to ounces (us fl oz) converter, which uses the reciprocal relationship.

Worked examples

Example: convert 2 fl oz to ml. Apply the formula — ml = fl oz × 29.5735 — and you get 59.15 ml. Reverse-check it by using the milliliters to ounces (us fl oz) to come back to 2 fl oz; if you do not land on the original number, a factor was inverted.

Example: convert 16 fl oz to ml. Apply the formula — ml = fl oz × 29.5735 — and you get 473.2 ml. Reverse-check it by using the milliliters to ounces (us fl oz) to come back to 16 fl oz; if you do not land on the original number, a factor was inverted.

Where the factor comes from

The US legal cup of 236.588 ml is the standard behind American recipes, defined from the US gallon (exactly 231 cubic inches). Australia, Canada and most of Europe use a metric cup of 250 ml — 5.7% larger. Spoon measures follow the same split: a US tablespoon is 14.79 ml versus the 15 ml metric tablespoon. Over a six-cup batch of dough, that difference is more than a third of a cup.

Common mistakes

US cup vs metric cup. Australian and Canadian recipes use a 250 ml cup. Baking a US recipe with metric cups over-measures every volume by 5.7%.

Tablespoon drift. A US tablespoon is 14.79 ml; a metric (Australian) tablespoon is 20 ml — 35% larger. This is the classic trap in recipes from UK/AU sources.

Packing brown sugar like flour. Volume charts assume the packing style stated. Brown sugar is measured packed, flour spooned-and-level — applying one style to both corrupts both.

Quick mental shortcuts

Mental shortcuts: cups → ml ≈ ×240 (exact 236.588); tbsp → ml ≈ ×15 (exact 14.79); tsp → ml ≈ ×5. Eight US fl oz is one cup; sixteen tablespoons are also one cup.

FAQ

How do I convert fl oz to ml?

Is this a US cup or a metric cup?

This converter uses the US legal cup of 236.588 ml, which is what US recipes mean by "cup". Metric cups (250 ml) are about 5.7% larger — worth remembering when baking from Australian or Canadian recipes.

Does ingredient density matter here?

No — this pair converts volume to volume, so the factor is fixed. Density only matters when converting between weight (grams, ounces) and volume (cups, milliliters).
