This converter allows you to convert fluid drams [Imp.fl.dr.] to US cups [US.cup] or US cups [US.cup] 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 cups
There are two simple ways to convert fluid drams [Imp.fl.dr.] to US cups [US.cup]. In the first calculation method, the value in fluid drams [Imp.fl.dr.] is divided by the rounded conversion factor of 66.6139. The second method multiplies the value in fluid drams [Imp.fl.dr.] by the rounded conversion factor of 0.015.
- US cups [US.cup] ≈ fluid drams [Imp.fl.dr.] ÷ 66.6139
- US cups [US.cup] ≈ fluid drams [Imp.fl.dr.] * 0.015
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 cups [US.cup] can be achieved using the following calculation method.
- US cups [US.cup] = fluid drams [Imp.fl.dr.] ÷ 483.87 ÷ 488.95 * 454,609 ÷ 128
Convert US cups to fluid drams
Converting US cups [US.cup] 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 cups [US.cup] is multiplied by the rounded conversion factor of 66.6139. The second variant is a division. Here, the value in US cups [US.cup] is divided by the rounded conversion factor of 0.015.
- Fluid drams [Imp.fl.dr.] ≈ US cups [US.cup] * 66.6139
- Fluid drams [Imp.fl.dr.] ≈ US cups [US.cup] ÷ 0.015
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 cups [US.cup] to fluid drams [Imp.fl.dr.] can be achieved using the following calculation method.
- Fluid drams [Imp.fl.dr.] = US cups [US.cup] * 483.87 * 488.95 ÷ 454,609 * 128
