Conversion formula

The conversion factor from gallons to cubic meters is 0.0037854118, which means that 1 gallon is equal to 0.0037854118 cubic meters:

1 gal = 0.0037854118 m3

To convert 120 gallons into cubic meters we have to multiply 120 by the conversion factor in order to get the volume amount from gallons to cubic meters. We can also form a simple proportion to calculate the result:

1 gal → 0.0037854118 m3

120 gal → V_(m3)

Solve the above proportion to obtain the volume V in cubic meters:

V_(m3) = 120 gal × 0.0037854118 m3

V_(m3) = 0.454249416 m3

The final result is:

120 gal → 0.454249416 m3

We conclude that 120 gallons is equivalent to 0.454249416 cubic meters:

120 gallons = 0.454249416 cubic meters
