America has two gallon systems and most cooks only know one: the liquid gallon in the milk jug, and the dry gallon used for grain, berries, and produce — and they are not the same size. The US dry gallon is 4.4048837 liters, about 15% larger than its liquid cousin, and it anchors a whole family of harvest units. Enter 1 in the Dry Gallons (US) box and the converter lays out the family: 4 Dry Quarts (US), 0.125 Bushels (US), 2 Pecks (US), and 4.4048837 Liters (L). The bushel is the star of the show — 8 dry gallons, the unit grain elevators and commodity markets still trade in — while the peck (2 dry gallons, or a quarter bushel) survives at farmers' markets, where a "peck of apples" is a real quantity with real heft. Colonial-era measures never fully died in American agriculture, so seed catalogs, harvest reports, and heritage recipes keep these units alive. The liter box translates it all for the metric world in one step.

With the pre-filled defaults — Dry Gallons (US) 1 — the Volume Dry Converter returns Dry Quarts (US) 4.00, Bushels (US) 0.1250, Pecks (US) 0.5000, Liters (L) 4.4049. Change any input and those results update instantly, so you can see exactly how each number you enter moves the answer.
