Convert fluid ounces to US fluid ounces
There are two simple ways to convert fluid ounces [Imp.fl.oz.] to US fluid ounces [US.fl.oz.]. In the first calculation method, the value in fluid ounces [Imp.fl.oz.] is divided by the rounded conversion factor of 1.0408. The second method multiplies the value in fluid ounces [Imp.fl.oz.] by the rounded conversion factor of 0.9608.
- US fluid ounces [US.fl.oz.] ≈ fluid ounces [Imp.fl.oz.] ÷ 1.0408
- US fluid ounces [US.fl.oz.] ≈ fluid ounces [Imp.fl.oz.] * 0.9608
However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of fluid ounces [Imp.fl.oz.] to US fluid ounces [US.fl.oz.] can be achieved using the following calculation method.
- US fluid ounces [US.fl.oz.] = fluid ounces [Imp.fl.oz.] ÷ 53.2257 ÷ 8,890 * 454,609
Convert US fluid ounces to fluid ounces
Converting US fluid ounces [US.fl.oz.] to fluid ounces [Imp.fl.oz.] is easy and can be done in two ways. The first method involves multiplication, in which the value in US fluid ounces [US.fl.oz.] is multiplied by the rounded conversion factor of 1.0408. The second variant is a division. Here, the value in US fluid ounces [US.fl.oz.] is divided by the rounded conversion factor of 0.9608.
- Fluid ounces [Imp.fl.oz.] ≈ US fluid ounces [US.fl.oz.] * 1.0408
- Fluid ounces [Imp.fl.oz.] ≈ US fluid ounces [US.fl.oz.] ÷ 0.9608
However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of US fluid ounces [US.fl.oz.] to fluid ounces [Imp.fl.oz.] can be achieved using the following calculation method.
- Fluid ounces [Imp.fl.oz.] = US fluid ounces [US.fl.oz.] * 53.2257 * 8,890 ÷ 454,609
