This converter allows you to convert quarts [Imp.qt.] to US gallons [US.liq.gal.] or US gallons [US.liq.gal.] to quarts [Imp.qt.]. 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 quarts to US gallons
There are two simple ways to convert quarts [Imp.qt.] to US gallons [US.liq.gal.]. In the first calculation method, the value in quarts [Imp.qt.] is divided by the rounded conversion factor of 3.3307. The second method multiplies the value in quarts [Imp.qt.] by the rounded conversion factor of 0.3002.
- US gallons [US.liq.gal.] ≈ quarts [Imp.qt.] ÷ 3.3307
- US gallons [US.liq.gal.] ≈ quarts [Imp.qt.] * 0.3002
However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of quarts [Imp.qt.] to US gallons [US.liq.gal.] can be achieved using the following calculation method.
- US gallons [US.liq.gal.] = quarts [Imp.qt.] ÷ 58,674 ÷ 258.064 * 4,546,090
Convert US gallons to quarts
Converting US gallons [US.liq.gal.] to quarts [Imp.qt.] 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 3.3307. The second variant is a division. Here, the value in US gallons [US.liq.gal.] is divided by the rounded conversion factor of 0.3002.
- Quarts [Imp.qt.] ≈ US gallons [US.liq.gal.] * 3.3307
- Quarts [Imp.qt.] ≈ US gallons [US.liq.gal.] ÷ 0.3002
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 quarts [Imp.qt.] can be achieved using the following calculation method.
- Quarts [Imp.qt.] = US gallons [US.liq.gal.] * 58,674 * 258.064 ÷ 4,546,090
