Liters to Cups Converter
Convert liters and cups in either direction while keeping the selected cup standard explicit.
Paste L, liters, cups, or c. A written metric cup or US cup overrides the cup standard; a bare cup uses the menu.
Liters to US customary cups
US customary cups = liters ÷ 0.2365882365. The underlying definition is exact: 1 US customary cup = 236.5882365 mL = 0.2365882365 L. Its reciprocal repeats: 1 L is approximately 4.22675283773 US customary cups and the tool displays up to 9 decimal places.
Liters to metric cups
Metric cups = liters ÷ 0.25. The exact relationship is 1 metric cup = 250 mL = 0.25 L, so 1 L = 4 metric cups. Choose Metric in the cup-standard menu or paste a value that includes “metric cup.”
Common liter values in both cup standards
| Liters | US customary cups | Metric cups |
|---|---|---|
| 0.25 L | ≈ 1.056688209 | 1 |
| 0.5 L | ≈ 2.113376419 | 2 |
| 1 L | ≈ 4.226752838 | 4 |
| 1.5 L | ≈ 6.340129257 | 6 |
| 2 L | ≈ 8.453505675 | 8 |
| 5 L | ≈ 21.133764189 | 20 |
Cups to liters
Liters = cups × liters per cup. Multiply US customary cups by 0.2365882365 or metric cups by 0.25. Swap carries the unrounded valid result into the reverse direction and preserves the active cup standard.
Which cup labels are accepted?
The input accepts a bare cup using the selected menu, US cup or U.S. customary cup for the US standard, and metric cup for the metric standard. Legal, FDA nutrition-label, and Imperial cups are rejected rather than silently converted. This page accepts liters and cups directly; use the related Milliliters to cups converter for mL inputs. It handles volume only and does not infer ingredient density or weight.
