The UK pint, quart, and gallon are all ~20% larger than their US counterparts. Always confirm which system a recipe or spec uses.
cm³ = ml exactly
1 cubic centimeter (cm³) and 1 milliliter (ml) are the same volume by definition. Medical syringes, lab glassware, and 3D printing volumes labelled in cm³ or ml are directly interchangeable no conversion needed.
Exact Formulas for Every Key Conversion
Use these to calculate manually or to sanity-check what the tool outputs
| Convert | Formula | Example |
|---|---|---|
| L → gal (US) | L ÷ 3.78541 | 10 L = 2.642 gal |
| gal → L | gal × 3.78541 | 5 gal = 18.93 L |
| ml → fl oz | ml ÷ 29.5735 | 355 ml = 12 fl oz |
| fl oz → ml | fl oz × 29.5735 | 8 fl oz = 236.6 ml |
| L → ml | L × 1,000 | 1.5 L = 1,500 ml |
| m³ → L | m³ × 1,000 | 2.5 m³ = 2,500 L |
| L → cup (US) | L × 4.22675 | 1 L = 4.227 cups |
| cup → ml | cup × 236.588 | 3 cups = 709.8 ml |
| ft³ → L | ft³ × 28.3168 | 10 ft³ = 283.2 L |
| ml → tsp | ml ÷ 4.92892 | 15 ml = 3.04 tsp |
| ml → tbsp | ml ÷ 14.7868 | 30 ml = 2.03 tbsp |
| cm³ → ml | 1:1 exactly | 250 cm³ = 250 ml |

Core Volume Conversions
Enter your liter (L) value, select L as the source unit the US gallon (gal) result appears instantly. Formula: L ÷ 3.78541 = US gal. Example: 10 L = 2.642 US gallons. Note: the UK/imperial gallon is different L ÷ 4.54609 = UK gal. Always confirm which gallon your context requires.
Exactly 1 liter (L) = 1,000 milliliters (ml). This is a fixed SI metric definition. In reverse: 1 ml = 0.001 L. Common references: 500 ml = 0.5 L (a standard water bottle); 330 ml ≈ 0.33 L (a soda can); 250 ml = 0.25 L (one US cup = ~236.6 ml, slightly less).
Cubic meters to liters: m³ × 1,000 = L. Example: 2.5 m³ = 2,500 L. Liters to cubic meters: L ÷ 1,000 = m³. Example: 500 L = 0.5 m³. This conversion is essential for tanks, swimming pools, rooms, and engineering calculations. 1 cubic meter (m³) holds exactly 1,000 liters.
1 US cup = 8 US fluid ounces (fl oz) = 236.588 ml. 1 liter = 33.814 US fluid ounces. UK note: 1 UK cup = 10 UK fl oz = 284.1 ml. Fluid ounce (fl oz) measures volume it is not the same as the weight ounce (oz). 1 US fl oz = 29.5735 ml; 1 UK fl oz = 28.4131 ml.
UntangleTools Volume Converter supports: milliliter (ml), centiliter (cl), deciliter (dl), liter (L), cubic centimeter (cm³), cubic meter (m³), teaspoon (tsp), tablespoon (tbsp), fluid ounce (fl oz), cup, pint (pt), quart (qt), US gallon (gal), UK gallon, and cubic foot (ft³). Type once, all units output simultaneously, one-click copy per row.
Three steps: (1) Enter any volume value integer or decimal into the input field. (2) Select your source unit from the dropdown: ml, L, m³, fl oz, cup, pint, quart, gallon, or ft³. (3) All supported output units update instantly. Tap the Copy icon next to any row to copy that value for use in recipes, reports, or code. No account, no install.
Multiply liters by 1,000: L × 1,000 = ml. Examples: 2 L = 2,000 ml; 0.5 L = 500 ml; 1.25 L = 1,250 ml. In reverse: ml ÷ 1,000 = L. The prefix "milli-" always means one-thousandth in the SI system so the same rule applies to every metric unit (mg, mm, ms, etc.).
ml to teaspoons: ml ÷ 4.92892 = tsp. Example: 15 ml = 3.04 tsp. ml to tablespoons: ml ÷ 14.7868 = tbsp. Example: 30 ml = 2.03 tbsp. In reverse: 1 tsp = 4.929 ml; 1 tbsp = 14.787 ml. Note: Australian tablespoon = 20 ml; UK tablespoon ≈ 17.76 ml; US tablespoon = 14.79 ml. International recipe discrepancies usually trace back to this difference.
1 US gallon = 3.78541 L. 1 UK (imperial) gallon = 4.54609 L. To convert: US gal × 1.20095 = UK gal (UK gallon is ~20% larger). UK gal × 0.832674 = US gal. This difference matters for fuel economy (mpg), large container purchases, and boat/vehicle fluid specs where US and UK manuals give different gallon figures.
Cubic meters to cubic feet: m³ × 35.3147 = ft³. Example: a 50 m³ room = 1,765.7 ft³. In reverse: ft³ × 0.0283168 = m³. For tanks: a 10 m³ water tank = 353.1 ft³ = 10,000 L = 2,641.7 US gallons. Useful when comparing HVAC specs (often in ft³/min) with metric room dimensions, or US aquarium gallons with metric tank sizes.
