A Cup Is Not a Cup Everywhere
The kitchen anchors: 1 US tablespoon is 14.79 ml (round to 15 for cooking), 1 US cup is 236.6 ml — not the 250 ml 'metric cup' that many measuring jug sets assume, a 6% gap that matters in baking. The classic trap is the gallon: a US gallon is 3.785 liters while a UK imperial gallon is 4.546 — 20% apart — so 10,000 US gallons is 37,854 liters, and any figure quoted 'in gallons' without a country attached is ambiguous by a fifth.
Two Gallon Systems, and Why Weight Beats Volume for Baking
The US customary and imperial systems are related but different: gallons differ by 20%, and fluid ounces differ along with them, so a conversion done with the wrong system's factor is silently wrong. US dry measures add a third layer — a dry quart is not a liquid quart. This is why serious baking advice ends the same way every time: convert to weight where possible. Volume conversions are the map; a kitchen scale is the territory.
About Volume Converter
Volume conversion lives in the kitchen more than anywhere else — American recipes speak in cups, tablespoons, and fluid ounces against the rest of the world's milliliters — but it reappears everywhere: pool owners calculating how many liters a '10,000-gallon' pool holds, travelers filling rental cars priced by the liter, and anyone comparing bottle sizes across US and European shelves. The stakes range from a failed cake to a badly wrong fuel budget.
