U.S. customary and metric conversions
Convert common distances, weights and volumes between U.S. customary and metric units. Temperature conversions use the exact Fahrenheit/Celsius relationship; U.S. gallons and fluid ounces are distinct from Imperial units.
For cooking, remember that converting volume to weight depends on the ingredient’s density. This tool converts volume units to volume units and does not infer ingredient weights.
