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 1000 gallons into cubic meters we have to multiply 1000 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

1000 gal → V_(m3)

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

V_(m3) = 1000 gal × 0.0037854118 m3

V_(m3) = 3.7854118 m3

The final result is:

1000 gal → 3.7854118 m3

We conclude that 1000 gallons is equivalent to 3.7854118 cubic meters:

1000 gallons = 3.7854118 cubic meters

Alternative conversion
