What is Quarts to Gallons Conversion?
Quarts and gallons are volume units used in different measurement systems. Quarts to gallons conversion converts a volume in quarts (qt) into an equivalent volume in gallons.
Because “gallon” can mean different things depending on the system, this converter shows three results: US gallons, UK (Imperial) gallons, and US dry gallons. That way, when you search qt to a gallon or quarts to the gallon, you can see the correct value for the system you need.
If you’re asking how many quarts to gallons, the standard relationship for US liquid is 1 US gallon = 4 US quarts. UK gallons and US dry gallons use different underlying volumes, so the conversion differs.
Quarts to Gallons Formula (US, UK, US Dry)
To convert quarts to gallons, divide quarts by the number of quarts per gallon for the target system. US liquid uses 4 quarts per US gallon. UK gallons and US dry gallons can be converted reliably by converting via liters.
Standard US liquid conversion: 1 US gallon = 4 US quarts.
Converts US liquid quarts to liters (1 qt = 0.946352946 L), then liters to UK gallons (1 UK gal = 4.54609 L).
Converts via liters to US dry gallons (1 US dry gal = 4.40488377086 L).
For US liquid, divide quarts by 4 to get US gallons.
So 8 quarts equals 2 US gallons (liquid).
So 8 US quarts is about 1.665 UK gallons (Imperial).
So 8 US quarts is about 1.72 US dry gallons.
