Need to convert a recipe from US cups to liters or milliliters? This calculator converts US customary cups to liters using the standard definition of one cup as 236.588 mL.

How It Works

The calculator multiplies your cup value by 0.236588 — the volume of one US customary cup in liters (236.588 mL ÷ 1,000). One US cup = 0.236588 liters exactly. This is useful for scaling recipes to metric volumes: 4 US cups equals approximately 0.946 liters (just under one liter), a convenient reference when working with large-batch cooking or converting US recipe volumes for metric measuring equipment. A standard metric measuring jug shows liters and milliliters — knowing that 1 US cup ≈ 237 mL makes it easy to measure cup amounts with metric equipment. Note that a metric cup (250 mL) differs from a US cup (236.588 mL), so results vary depending on which standard your recipe uses.
