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 300 gallons into cubic meters we have to multiply 300 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

300 gal → V_(m3)

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

V_(m3) = 300 gal × 0.0037854118 m3

V_(m3) = 1.13562354 m3

The final result is:

300 gal → 1.13562354 m3

We conclude that 300 gallons is equivalent to 1.13562354 cubic meters:

300 gallons = 1.13562354 cubic meters
