1 U.S. gallon = 3.79 L

1 L occupies a space of $1 {\mathrm{dm}}^{3}$ ($1 {\mathrm{dm}}^{3}$ measures 10 cm, or approximately 4 in, on each side of the cube.)

It takes 1 000 ${\mathrm{dm}}^{3}$ to make up $1 {m}^{3}$ (Each side of the cube measures 10 dm.)

Therefore:

1 gal (U.S.) = 3.79 x ${10}^{-} 3 {m}^{3}$

If you are wanting to convert in the opposite direction, $1 {m}^{3}$ = 264.17 gal (U.S.), according to the UnitConvertLT app.

For imperial (U.K.) gallons, the conversion is

1 gal (U.K.) = 4.546 L.

The same process would be used for converting it to cubic metres.

If you are wanting to convert in the opposite direction, $1 {m}^{3}$ = 219.97 gal (U.K.), according to the UnitConvertLT app.
