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 340 gallons into cubic meters we have to multiply 340 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

340 gal → V_(m3)

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

V_(m3) = 340 gal × 0.0037854118 m3

V_(m3) = 1.287040012 m3

The final result is:

340 gal → 1.287040012 m3

We conclude that 340 gallons is equivalent to 1.287040012 cubic meters:

340 gallons = 1.287040012 cubic meters
