Formulas for converting quarts to liters
A quart (qt) is a volume unit equal to one quarter of a gallon. There are several definitions in current use:
- US liquid quart – used for beverages and most kitchen liquids.
- US dry quart – used for dry foods like grains and berries.
- Imperial (UK) quart – used in the British Imperial system.
A liter (L) is a metric unit of volume equal to 1,000 cubic centimeters (0.001 m³).
Quarts to liters (forward conversion)
The general pattern is:
\[ \text{liters} = \text{quarts} \times \text{factor} \]
where the factor depends on the type of quart:
- US liquid: \(\text{L} \approx \text{qt} \times 0.946353\)
- US dry: \(\text{L} \approx \text{qt} \times 1.10122\)
- Imperial: \(\text{L} \approx \text{qt} \times 1.13652\)
Liters to quarts (reverse conversion)
To convert back from liters to quarts, divide by the same factor:
- US liquid: \(\text{qt} \approx \dfrac{\text{L}}{0.946353}\)
- US dry: \(\text{qt} \approx \dfrac{\text{L}}{1.10122}\)
- Imperial: \(\text{qt} \approx \dfrac{\text{L}}{1.13652}\)
Worked examples
-
Example 1 – 2 US liquid quarts to liters
\[ \text{L} \approx 2 \times 0.946353 \approx 1.8927\ \text{L} \] So half a gallon of milk is roughly 1.9 liters. -
Example 2 – 3 liters to US liquid quarts
\[ \text{qt} \approx \dfrac{3}{0.946353} \approx 3.17\ \text{qt} \] A 3 L pot holds just over 3 US quarts. -
Example 3 – 4 Imperial quarts to liters
\[ \text{L} \approx 4 \times 1.13652 \approx 4.5461\ \text{L} \] This is exactly one Imperial gallon.
Choosing the right quart type
Many simple online tools assume US liquid quarts only. That is usually fine for US recipes and grocery packaging, but it becomes inaccurate when:
- You convert old British recipes written in Imperial units.
- You work with dry ingredients measured in US dry quarts.
- You compare labels or specs from different countries.
This calculator lets you explicitly choose between US liquid, US dry, and Imperial quarts, so your conversions stay trustworthy even in edge cases.
Quarts, pints, cups and liters – quick mental shortcuts
- 1 US liquid quart = 2 pints = 4 cups ≈ 0.95 L.
- 2 US quarts ≈ 1.9 L (often rounded to “about 2 liters”).
- 4 US quarts ≈ 3.8 L (one US gallon).
- 1 liter ≈ 1.06 US quarts (just slightly more than one quart).
If you just need an approximate conversion in your head, you can treat 1 quart ≈ 1 liter. For labeling, nutrition, or process engineering, always use the precise factors.
FAQ: quarts to liters
Which quart should I use for cooking conversions?
For modern cookbooks from the US, you almost always want the US liquid quart. Older UK recipes may implicitly use Imperial quarts, which are larger. When in doubt, check the source country or convert everything to liters.
Why are my liter values slightly different from package labels?
Many products round to “nice” volumes (like 1 L, 1.5 L, 2 L) instead of exact quart equivalents. That means working backwards from the label will not give a perfect integer number of quarts. Use the calculator to get accurate conversions, and treat labels as approximate for quart values.
Can I use this converter for scientific or lab work?
Yes, as long as you pick the correct quart type and keep enough decimal places in the result. For high-precision work, you might still prefer to measure directly in milliliters or liters using calibrated glassware.
