Formula
1 L = 1 000 mL = 0,001 m³ = 0,0353147 ft³ = 0,264172 gal(US) = 0,219969 gal(UK) = 33,814 fl oz = 4,22675 cups
About this calculator
The Volume Converter is a practical tool for converting between major volume units: liter, milliliter, cubic meter, cubic foot, gallon (US and imperial), fluid ounce, and cup. It uses precise conversion factors, such as 1 liter = 1000 mL = 0.001 m³ = 0.0353147 ft³ = 0.264172 gal (US) = 0.219969 gal (UK) = 33.814 fl oz = 4.22675 cups. Simply enter the value in the source unit and select the target unit to get the result instantly.
This calculator is useful in many everyday situations: cooking recipes with different measures, calculating container capacities, scientific experiments, construction projects for concrete volumes, or comparing fuel prices across countries. It eliminates the need to memorize conversion factors and avoids manual errors.
Important caveats: check whether you are using US or imperial gallons, as the difference is significant (1 US gal ≈ 3.785 L, 1 UK gal ≈ 4.546 L). Note that fluid ounces and cups vary between systems (US vs UK); this tool adopts standard US values for cup (240 mL) and fl oz (29.5735 mL), but you can adjust if needed. Always confirm that the target unit matches your context (e.g., Brazilian recipes usually use mL and L).
Frequently asked questions
What is the difference between US gallon and imperial gallon?
The US gallon equals approximately 3.785 liters, while the imperial gallon (used in the UK) equals about 4.546 liters. The difference is about 20%.
How many milliliters are in a cup?
A standard US cup has 240 mL. In Brazil, the tea cup also has 240 mL, but coffee cups may vary. This tool uses 240 mL as default.
How do I convert cubic feet to liters?
Multiply the value in cubic feet by 28.3168 to get liters. For example, 1 ft³ = 28.3168 L.
Does this tool convert fluid ounces to milliliters?
Yes. The US fluid ounce (fl oz) equals 29.5735 mL. The imperial one is 28.4131 mL. The converter uses the US standard, but you can adjust manually if needed.
Can I use this calculator for cooking recipes?
Yes, it is useful for converting measures in international recipes. Remember that cups and spoons may vary by region; check if the recipe uses the US system or another.
