A US gallon is 3.785 liters, the standard unit for fuel and milk sold by volume in the US. A US quart is 2 pints, about 946 milliliters, used for milk, oil, and food storage containers in the US. 1 gal equals 4 qt, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to volume, measured here against volume's base unit (L) — every other volume unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
qt = gal × 4
gal = qt × 0.25
