This converter allows you to convert fluid drams [Imp.fl.dr.] to US fluid ounces [US.fl.oz.] or US fluid ounces [US.fl.oz.] to fluid drams [Imp.fl.dr.]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.
Convert fluid drams to US fluid ounces
There are two simple ways to convert fluid drams [Imp.fl.dr.] to US fluid ounces [US.fl.oz.]. In the first calculation method, the value in fluid drams [Imp.fl.dr.] is divided by the rounded conversion factor of 8.3267. The second method multiplies the value in fluid drams [Imp.fl.dr.] by the rounded conversion factor of 0.1201.
- US fluid ounces [US.fl.oz.] ≈ fluid drams [Imp.fl.dr.] ÷ 8.3267
- US fluid ounces [US.fl.oz.] ≈ fluid drams [Imp.fl.dr.] * 0.1201
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 drams [Imp.fl.dr.] to US fluid ounces [US.fl.oz.] can be achieved using the following calculation method.
- US fluid ounces [US.fl.oz.] = fluid drams [Imp.fl.dr.] ÷ 53.2257 ÷ 555.625 * 454,609 ÷ 128
Convert US fluid ounces to fluid drams
Converting US fluid ounces [US.fl.oz.] to fluid drams [Imp.fl.dr.] 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 8.3267. The second variant is a division. Here, the value in US fluid ounces [US.fl.oz.] is divided by the rounded conversion factor of 0.1201.
- Fluid drams [Imp.fl.dr.] ≈ US fluid ounces [US.fl.oz.] * 8.3267
- Fluid drams [Imp.fl.dr.] ≈ US fluid ounces [US.fl.oz.] ÷ 0.1201
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 drams [Imp.fl.dr.] can be achieved using the following calculation method.
- Fluid drams [Imp.fl.dr.] = US fluid ounces [US.fl.oz.] * 53.2257 * 555.625 ÷ 454,609 * 128
