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 20.7 gallons into cubic meters we have to multiply 20.7 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

20.7 gal → V_(m3)

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

V_(m3) = 20.7 gal × 0.0037854118 m3

V_(m3) = 0.07835802426 m3

The final result is:

20.7 gal → 0.07835802426 m3

We conclude that 20.7 gallons is equivalent to 0.07835802426 cubic meters:

20.7 gallons = 0.07835802426 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 12.761934842587 × 20.7 gallons.

Another way is saying that 20.7 gallons is equal to 1 ÷ 12.761934842587 cubic meters.

Approximate result

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

20.7 gal ≅ 0.078 m3

An alternative is also that one cubic meter is approximately twelve point seven six two times twenty point seven gallons.
