Tips for volume conversions
The US gallon (3.785 L) is 17% smaller than the UK imperial gallon (4.546 L). Fuel economy figures depend on which gallon is used.
A litre of water weighs exactly 1 kg at 4 °C — one of the most elegant metric relationships.
US cup (240 ml) and UK cup (284 ml) are different. Metric cup (250 ml) is a third variant common in Australia and New Zealand.
Fluid ounces (volume) and ounces (mass) are different units. Always check the context.
Common mistakes to avoid
Confusing US and UK gallons in fuel-economy comparisons — 30 mpg (US) equals 36 mpg (UK).
Assuming 1 cup is universally 240 ml — US, UK, metric and Japanese cups all differ.
Mixing up fluid ounces (~29.6 ml in US) with mass ounces (28.35 g).
Using cubic centimetres and millilitres interchangeably in precision medicine — they are the same (1 cc = 1 ml), but the context matters.
