About US Cup to US Pint Conversion

Converting us cup to us pint comes up frequently in cooking, chemistry, medicine, and engineering. A recipe written in metric units may need to be adapted for a kitchen using us pint, or a laboratory protocol may specify volumes in us cup that need to be measured with equipment calibrated in us pint.

In everyday use, knowing that 5 cup = 2.5 pt and 10 cup = 5 pt covers most common situations. For bulk calculations, 100 cup = 50 pt is a useful anchor. The reverse conversion — us pint back to us cup — uses the factor 2, so 1 pt = 2 cup.

All conversions use the internationally recognized factor of exactly 1 cup = 0.5 pt. Calculations are performed in IEEE 754 double-precision floating point, giving accuracy to at least 8 significant figures — more than sufficient for any practical application.

Quick Answer

Formula: US Pint = US Cup × 0.5

Multiply any us cup value by 0.5 to get us pint. One us cup equals 0.5 pt.

Worked Examples

One US pint
2 cup × 0.5 = 1 pt
2 US cups = 1 US pint.
One US cup
1 cup × 0.5 = 0.5 pt
1 cup = 0.5 US pints.
One US gallon
16 cup × 0.5 = 8 pt
16 cups = 8 pints = 1 US gallon.
One US quart
4 cup × 0.5 = 2 pt
4 cups = 2 pints = 1 quart.
