Background

Volume conversion is essential in cooking, chemistry, engineering, and fuel measurement. The litre is standard metric; gallons, cups, and fl oz are US/imperial. US and imperial gallons differ by 20%.

US vs Imperial Gallons

US gallon = 3.785 L; imperial = 4.546 L — a 20% difference. Australia uses litres.

Cups and Cooking

US cup = 236.6 ml; Australian metric cup = 250 ml. Small differences matter in baking.

Applications

Cooking and Baking

2 cups of milk ≈ 473 ml (US) or 500 ml (metric). The difference matters in baking.

Fuel and Automotive

Fuel efficiency: L/100km (AU) vs MPG (US). Requires both volume and distance conversions.

Chemistry and Pharma

Lab measurements require precise volume conversions. µl, ml, and L conversions are routine.
