Volume Converter
Convert between Liters, Gallons, Cups, mL, and Cubic Meters.
Volume measures the 3D space occupied by a substance. It is crucial for cooking (teaspoons to cups), fuel efficiency (gallons vs liters), and science. Note that US Customary units for volume (fluid ounces, gallons) are slightly different from Imperial units used in the UK.

Frequently Asked Questions
Volume Facts
1. Fluid Ounce vs. Ounce
This is the most common confusion in the kitchen. A "Fluid Ounce" (fl oz) measures volume (space). An "Ounce" (oz) measures weight. For water, they are close (1 fl oz weighs ≈ 1.04 oz), but for honey or flour, they are very different.
2. Gallon Confusion
Be careful when traveling! A US Gallon is 3.78 Liters. An Imperial (UK) Gallon is 4.54 Liters (~20% larger). This often tricks drivers calculating MPG across borders.
