Common Questions

How many milliliters are in a fluid ounce?+

One US fluid ounce is 29.5735 milliliters. That figure is exact by US customary measure. When a formula card lists 1 oz of an ingredient, you need 29.57 ml, not 30. The rounding difference matters at scale.

Is cc the same as ml?+

Yes. For liquid measurement, one cubic centimeter and one milliliter are identical: both are one thousandth of a liter. Pharmaceutical and medical contexts tend to use cc; the cosmetics and beverage industries almost always use ml. The converter treats them as the same unit.

What is 100ml in fluid ounces?+

100 ml converts to 3.38 fl oz. Two reasons that number matters: it is the TSA carry-on limit for liquids, and it is the most common size for prestige skincare and fragrance travel formats.

What does 1 liter equal in fluid ounces?+

One liter is 33.81 fl oz. Large-format refill bottles, professional salon sizes, and household cleaning products commonly come in 1-liter packaging. US retailers label these as the 33.8 oz size.

How many ml is a US gallon?+

One US gallon is 3,785.41 ml, or 3.785 liters. This is different from the imperial gallon used in the UK and Canada, which is 4,546 ml. All conversions in this tool use the US gallon.

What is a fluid dram?+

A fluid dram is 3.697 ml in US measure. It appears in pharmaceutical compounding, perfume blending, and essential oil formulation. Most packaging buyers will not encounter it unless they work with apothecary or custom fragrance products.
