666 mm³ = 0.0001465 gal (Imperial; in US gallons: 666 mm³ = 0.000175939 US gal). To convert cubic millimeters to gallons, multiply by 2.1996935 × 10^-7: 666 × 2.1996935 × 10^-7 = 0.0001465.
How to convert cubic millimeters to gallons
gal = mm³ × 2.1996935 × 10^-7
- 1 mm³ = 2.1996935 × 10^-7 gal (and 1 gal = 4,546,087.9 mm³).
- Multiply the amount by the factor: 666 × 2.1996935 × 10^-7 = 0.0001465.
- Answer: 666 mm³ = 0.0001465 gal.
