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 4.2 gallons into cubic meters we have to multiply 4.2 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

4.2 gal → V_(m3)

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

V_(m3) = 4.2 gal × 0.0037854118 m3

V_(m3) = 0.01589872956 m3

The final result is:

4.2 gal → 0.01589872956 m3

We conclude that 4.2 gallons is equivalent to 0.01589872956 cubic meters:
