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 20 gallons into cubic meters we have to multiply 20 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

20 gal → V_(m3)

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

V_(m3) = 20 gal × 0.0037854118 m3

V_(m3) = 0.075708236 m3

The final result is:

20 gal → 0.075708236 m3

We conclude that 20 gallons is equivalent to 0.075708236 cubic meters:

20 gallons = 0.075708236 cubic meters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 cubic meter is equal to 13.208602562078 × 20 gallons.

Another way is saying that 20 gallons is equal to 1 ÷ 13.208602562078 cubic meters.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that twenty gallons is approximately zero point zero seven six cubic meters:

20 gal ≅ 0.076 m3

An alternative is also that one cubic meter is approximately thirteen point two zero nine times twenty gallons.
