How it’s calculated
A US liquid quart is exactly 4 US cups (946.35 mL). An imperial quart is 1.1365 L, about 20% larger, and holds 4 imperial cups.
1 cup (US) = 0.25 qt (US) (exact) · 1 qt (US) = 4 cup (US) (exact)
qt (US) = cup (US) × 0.25
- Multiply the value in US cups by 0.25.
- To go back, divide by 0.25 (or multiply by 4).
- 1 cup (US) = 0.25 qt (US) · 1 qt (US) = 4 cup (US)
Step by step
Find the conversion factor
By definition 1 cup (US) = 0.0002365882365 m³ and 1 qt (US) = 0.000946352946 m³, so 1 qt (US) = 4 cup (US). Source: NIST SP 811 / Handbook 44.
