Convert 20 liters to gallons (US)

Explanation

Let's convert 20 liters to gallons (US), or l to gal as one could put it.

First, we need to calculate the conversion factor using the units respective values. We find 0.2642.

Then we multiply this conversion factor by the number of liters. In this case 20.

Therefore, 20 liters is approximately equal to 5.2834 gallons (US).

Formula

1 l≈0.2642 gal

20 l≈20 × 0.2642 gal

20 l≈5.2834 gal
