How much liter in 1gallon?

Answer 1

Approximately 4 Liters..

Some gallons and volumes.

In United States customary units there are the liquid (≈ 3.79 L) and the lesser used dry gallons (≈ 4.4 L). There is also the imperial gallon (≈ 4.55 L) which is in unofficial use within the United Kingdom and Ireland and is in semi-official use within Canada.

Answer 2

Liters and gallons are both volume measurements where

1 US gallons = 3.78541178913203 liters

1 Imperial gallons = 4.54609188687303 liters

This question makes no sense.
