This converter allows you to convert cubic feet [ft³] to US gallons [US.liq.gal.] or US gallons [US.liq.gal.] to cubic feet [ft³]. 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 feet to US gallons
There are two simple ways to convert cubic feet [ft³] to US gallons [US.liq.gal.]. In the first calculation method, the value in cubic feet [ft³] is divided by the rounded conversion factor of 0.1337. The second method multiplies the value in cubic feet [ft³] by the rounded conversion factor of 7.4805.
- US gallons [US.liq.gal.] ≈ cubic feet [ft³] ÷ 0.1337
- US gallons [US.liq.gal.] ≈ cubic feet [ft³] * 7.4805
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 feet [ft³] to US gallons [US.liq.gal.] can be achieved using the following calculation method.
- US gallons [US.liq.gal.] = cubic feet [ft³] ÷ 58,674 ÷ 64.516 * 304.83
Convert US gallons to cubic feet
Converting US gallons [US.liq.gal.] to cubic feet [ft³] 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 0.1337. The second variant is a division. Here, the value in US gallons [US.liq.gal.] is divided by the rounded conversion factor of 7.4805.
- Cubic feet [ft³] ≈ US gallons [US.liq.gal.] * 0.1337
- Cubic feet [ft³] ≈ US gallons [US.liq.gal.] ÷ 7.4805
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 feet [ft³] can be achieved using the following calculation method.
- Cubic feet [ft³] = US gallons [US.liq.gal.] * 58,674 * 64.516 ÷ 304.83
