How Much Is 30 mL? Ounces, Tablespoons and What It Looks Like

30 millilitres equals 1.01 US fluid ounces, 2 tablespoons, or 6 teaspoons — almost exactly one fluid ounce, which is why “1 oz” bottles actually contain 30 ml. It is one of the most common sizes in packaging: the standard small perfume, the typical serum bottle, a double espresso shot’s volume, a standard dose cup of cough syrup. Here is 30 ml in every unit, with the exact maths and the packaging context.

For any other value, our oz ↔ mL converter does the arithmetic both ways, and the mL to cups guide covers kitchen measures.

What 30 mL looks like

Mental pictures help more than decimals. 30 ml is: two tablespoons of liquid; a double espresso (a standard double is 60 ml, so half of one); the typical dose cup supplied with liquid medicines; a standard hotel shampoo bottle; and the classic small perfume bottle. In a kitchen, it is a generous glug of olive oil; at a bar, it is the standard spirit measure in several countries (Germany and Australia pour 30 ml shots).

Where 30 mL appears in packaging

• Perfume: 30 ml (1 oz) is the entry full size — see the perfume bottle size guide.
• Skincare: the standard serum and facial-oil bottle, usually with a dropper — see dropper bottle sizes.
• Travel: comfortably under the 100 ml cabin limit; the common size for minis and amenity kits.
• Pharma: a standard bottle for tinctures and paediatric medicines, where the ~600-drop content matters for dosing.
• Spirits: close to the 50 ml miniature but below it; 30 ml appears as an airline or sampling pour rather than a bottle size — the bottle ladder is in the liquor bottle size guide.

The exact maths

One US fluid ounce is defined as 29.5735295625 ml. So 30 ml ÷ 29.5735295625 = 1.0144 fl oz. A US tablespoon is ½ fl oz = 14.7868 ml, so 30 ml = 2.0289 tbsp. The rounding all goes one way: a “1 oz” bottle filled with 30 ml contains slightly more than an ounce, never less — which is why the label is legal in fill terms.

Frequently asked questions

Is 30 mL the same as 1 oz?

Practically yes: 30 ml is 1.014 US fluid ounces. Bottles labelled 1 oz contain 30 ml. For exact work, one fluid ounce is 29.57 ml.

How many tablespoons is 30 mL?

Two US tablespoons (2.03 exactly). In cooking, treat 30 ml and 2 tablespoons as interchangeable.

How many teaspoons is 30 mL?

Six US teaspoons (6.09 exactly). A teaspoon is about 4.93 ml.

Is 30 mL a shot?

It depends where you are. Germany, Australia and several other countries pour 30 ml as the standard shot. The common US shot is 1.5 oz (44 ml), so 30 ml is a small pour there.

How many drops is 30 mL?

About 600, at the pharmacy convention of 20 drops per ml. Real counts vary between roughly 450 and 750 depending on the liquid’s viscosity and the dropper tip.

How big is a 30 mL bottle?

Capacity does not fix dimensions — a 30 ml perfume flacon, serum bottle and pharma round all differ in height and diameter. Typical serum bottles run about 35–40 mm diameter and 90–100 mm tall. Always work from the manufacturer’s drawing, as explained in our packaging dimensions guide.
