Convert between milliliters, ounces, cups, liters, and more
Our converter uses milliliters (ml) as the base unit. All conversions first convert to ml, then to your target unit. This ensures accuracy and consistency across all measurements.
The metric system (ml, liters) is used worldwide and based on powers of 10. The US customary system (ounces, cups, gallons) has different conversion factors. This calculator handles both seamlessly.
This calculator uses US customary measurements. UK/Imperial measurements differ slightly (e.g., UK fluid ounce = 28.4131 ml). For cooking, these small differences usually don't matter, but be aware if precision is critical.
Convert recipe measurements between metric and imperial. Essential when using international recipes or adjusting serving sizes.
Know if your liquids meet the 3.4 oz (100 ml) TSA limit. Convert bottle sizes to ensure airport security compliance.
Convert cocktail recipes from ml to oz or vice versa. Understand jigger sizes and standard pours (1.5 oz = 44 ml).
Convert liquid medication doses accurately. Know that 1 teaspoon = 5 ml for proper dosing (though always follow your doctor's instructions).
