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 420 gallons into cubic meters we have to multiply 420 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

420 gal → V_(m3)

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

V_(m3) = 420 gal × 0.0037854118 m3

V_(m3) = 1.589872956 m3

The final result is:

420 gal → 1.589872956 m3

We conclude that 420 gallons is equivalent to 1.589872956 cubic meters:
