What a 5-gallon container holds in liters

5 US gallons is 18.93 liters, the size of the common US 5-gallon bucket and the large water-cooler bottle. If a source means imperial gallons, the same "5 gallons" is 22.73 liters, about a fifth more.

Container or unit	US gallons	Liters
5 US gallons	5	18.93 L
5 imperial gallons	6.00	22.73 L
19-liter water bottle	5.02	19 L
20-liter jerrycan	5.28	20 L

Filled with water, 5 US gallons weigh about 18.9 kg (41.7 lb), so a full bucket is a two-handed lift.
A 20-liter jerrycan holds 5.28 US gallons. Emptying a full one into a 5-gallon bucket overflows it by about 1.1 liters.
Older British or Commonwealth figures that say 5 gallons mean 22.73 liters, not 18.93.
A product dosed at one capful per US gallon needs 5 capfuls for a full bucket, but only about 4 if the bucket holds 15 liters.

Rounding 18.93 L to 19 L is off by only 0.4%; calling it 20 L overstates the volume by 5.7%.
