The US fluid ounce is a unit of liquid volume equal to 1/128 of a US gallon, or approximately 29.574 milliliters.
1 US fl oz = 2 US tbsp = 6 US tsp = 1/8 US cup = 29.5735 mL.
To mL: multiply by 29.5735. To UK fluid ounces: multiply by 1.04084. To tablespoons (US): multiply by 2.
Beverage cans (12 fl oz), water bottles (16.9 fl oz), coffee sizes, medicine dosing, and shampoo bottles.
A US fluid ounce of water weighs almost exactly 1 avoirdupois ounce (29.57 mL ≈ 28.35 g). The UK fl oz is slightly smaller (28.41 mL).
Confusing fluid ounces (volume) with ounces (weight). Also, US and UK fluid ounces differ slightly.
1 fl oz ≈ 30 mL (close enough). A soda can = 12 fl oz. A standard water bottle = 16.9 fl oz ≈ 500 mL.
The femtoliter is a unit of volume equal to 10⁻¹⁵ liters, or one quadrillionth of a liter.
1 fL = 10⁻¹⁵ L = 10⁻¹² mL = 1,000 aL = 1 µm³ (cubic micrometer).
To liters: multiply by 10⁻¹⁵. To picoliters: divide by 1,000. To attoliters: multiply by 1,000.
Measuring red blood cell volumes (normal MCV: 80–100 fL), inkjet droplet sizes, and flow cytometry particle analysis.
A human red blood cell has a volume of about 90 fL. The smallest inkjet droplets are in the range of 1–5 fL.
Assuming fL is too small to be practical — it is actually the standard unit used on every complete blood count (CBC) lab report.
Remember: fL = femtoliter, the volume of blood cells. Normal MCV range: 80–100 fL. It's a key clinical measurement.
