The first method involves multiplication, in which the value in gallons [Imp.gal.] is multiplied by the rounded conversion factor of 1.091 * 10-12. The second variant is a division. Here, the value in gallons [Imp.gal.] is divided by the rounded conversion factor of 9.169 * 1011.

  • Cubic miles [mi³] ≈ gallons [Imp.gal.] * 1.091 * 10-12
  • Cubic miles [mi³] ≈ gallons [Imp.gal.] ÷ (9.169 * 1011)

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of gallons [Imp.gal.] to cubic miles [mi³] can be achieved using the following calculation method.

  • Cubic miles [mi³] = gallons [Imp.gal.] * 4,546,090 ÷ 1,609,3443
