This converter allows you to convert liters [l] to gallons [Imp.gal.] or gallons [Imp.gal.] to liters [l]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 liter [l] ≈ 0.22 gallons [Imp.gal.]1 gallon [Imp.gal.] ≈ 4.5461 liters [l]

Convert liters to gallons

There are two simple ways to convert liters [l] to gallons [Imp.gal.]. In the first calculation method, the value in liters [l] is divided by the rounded conversion factor of 4.5461. The second method multiplies the value in liters [l] by the rounded conversion factor of 0.22.

  • Gallons [Imp.gal.] ≈ liters [l] ÷ 4.5461
  • Gallons [Imp.gal.] ≈ liters [l] * 0.22

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of liters [l] to gallons [Imp.gal.] can be achieved using the following calculation method.

  • Gallons [Imp.gal.] = liters [l] ÷ 454,609 * 105

Convert gallons to liters

Converting gallons [Imp.gal.] to liters [l] is easy and can be done in two ways. The first method involves multiplication, in which the value in gallons [Imp.gal.] is multiplied by the rounded conversion factor of 4.5461. The second variant is a division. Here, the value in gallons [Imp.gal.] is divided by the rounded conversion factor of 0.22.

  • Liters [l] ≈ gallons [Imp.gal.] * 4.5461
  • Liters [l] ≈ gallons [Imp.gal.] ÷ 0.22

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 liters [l] can be achieved using the following calculation method.

  • Liters [l] = gallons [Imp.gal.] * 454,609 ÷ 105
