Kitchen volume splits into two rival traditions: the metric liter family and the US customary set built on the gallon. The US cup holds 236.588 ml — rounded to 240 ml (0.24 L) in nutrition labeling, which is the factor this converter uses — sixteen tablespoons fill it, and two cups make a pint — ratios that matter when baking precision counts.
Watch out for UK recipes: the imperial pint runs 20 fluid ounces rather than America's 16, a difference that quietly wrecks older British recipes converted carelessly. This converter uses US definitions throughout.
The tablespoon trap: US tablespoons are 14.79 ml, UK/Australian tablespoons are 15 ml (close enough), but the Australian tablespoon is 20 ml — a 35% overdose on leavening that ruins cakes. Dessert spoons (≈10 ml) and soup spoons (variable) are not tablespoons at all; use real measuring spoons.
Fluid ounces versus weight ounces share a name and nothing else: 8 fl oz of water weighs 8 oz, but 8 fl oz of honey weighs ~12 oz and 8 fl oz of flour ~4.3 oz. Volume-to-weight needs density per ingredient — the number-one baking conversion error.
Scaling recipes multiplies error: doubling is safe, but halving thirds (⅓ cup → tablespoons) and scaling yeast, salt and leavening non-linearly breaks results. Convert first, then scale the metric result; never scale in mixed units.
Fuel and automotive volumes use the same math at different scales: US gallons (3.785 L) versus imperial gallons (4.546 L) make 'miles per gallon' incomparable across the Atlantic — 30 mpg US ≈ 36 mpg imperial. Always note which gallon a figure uses.
Convert liters, gallons, cups, tablespoons and other volume measures. Formula: result = value × (from-factor ÷ to-factor), anchored on liters. Example: 2.5 liters of broth equals about 10.42 US cups (2.5 ÷ 0.24), or 84.5 fluid ounces — useful when halving a stockpot recipe into smaller pots.
