This converter allows you to convert cubic decimeters [dm³] to US gallons [US.liq.gal.] or US gallons [US.liq.gal.] to cubic decimeters [dm³]. 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 cubic decimeters to US gallons
There are two simple ways to convert cubic decimeters [dm³] to US gallons [US.liq.gal.]. In the first calculation method, the value in cubic decimeters [dm³] is divided by the rounded conversion factor of 3.7854. The second method multiplies the value in cubic decimeters [dm³] by the rounded conversion factor of 0.2642.
- US gallons [US.liq.gal.] ≈ cubic decimeters [dm³] ÷ 3.7854
- US gallons [US.liq.gal.] ≈ cubic decimeters [dm³] * 0.2642
However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of cubic decimeters [dm³] to US gallons [US.liq.gal.] can be achieved using the following calculation method.
- US gallons [US.liq.gal.] = cubic decimeters [dm³] ÷ 586.74 ÷ 645.16 * 105
Convert US gallons to cubic decimeters
Converting US gallons [US.liq.gal.] to cubic decimeters [dm³] is easy and can be done in two ways. The first method involves multiplication, in which the value in US gallons [US.liq.gal.] is multiplied by the rounded conversion factor of 3.7854. The second variant is a division. Here, the value in US gallons [US.liq.gal.] is divided by the rounded conversion factor of 0.2642.
- Cubic decimeters [dm³] ≈ US gallons [US.liq.gal.] * 3.7854
- Cubic decimeters [dm³] ≈ US gallons [US.liq.gal.] ÷ 0.2642
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 gallons [US.liq.gal.] to cubic decimeters [dm³] can be achieved using the following calculation method.
- Cubic decimeters [dm³] = US gallons [US.liq.gal.] * 586.74 * 645.16 ÷ 105
