Volume Formulas

fl oz to mL

mL = fl oz × 29.5735

The fundamental multiplier for metric translation.

mL to fl oz

fl oz = mL ÷ 29.5735

The precision ratio for US volumetric standards.

The Volumetric Constant

The fluid ounce is a unit of volume in both the US Customary and Imperial systems, though they differ slightly. The US Fluid Ounce, used in our converter, is defined as exactly 1/128 of a US gallon, which translates to approximately 29.57 mL.

1 fl oz = 29.5735295625 mL

This high-precision constant is critical in laboratory settings and international trade where small deviations in volume can impact product consistency or chemical safety.

In technical environments, the distinction between "fluid ounces" and "ounces of weight" is paramount. Fluid ounces measure space, while dry ounces measure mass.

Our converter ensures that your liquid formulations and culinary measurements remain perfectly aligned with the NIST standards for volumetric accuracy.

Standard: 1 US Cup = 8 fl oz ≈ 236.59 mL
