📖 About Oz to Cups
Culinary Baking Volumetric Metrology & NIST Standards
The standard US Customary measuring cup is defined as exactly 8 fluid ounces (16 tablespoons or 48 teaspoons):
- 1 US Customary Cup: 8.0 US fl oz = 16.0 US Tbsp = 48.0 US tsp = 236.588 mL = (1) / (2) US Pint
- 1 Metric Cup (Commonwealth): 250.0 mL = 8.454 US fl oz
- 1 US Legal Cup (Nutrition): 240.0 mL = 8.115 US fl oz
Primary Kitchen Cup & Fluid Ounce Equivalents
- 2.0 fl oz: (1) / (4) Cup = 4.0 Tbsp = 59.15 mL
- 2.67 fl oz: ≈ (1) / (3) Cup = 5 (1) / (3) Tbsp = 78.86 mL
- 4.0 fl oz: (1) / (2) Cup = 8.0 Tbsp = 118.29 mL
- 6.0 fl oz: (3) / (4) Cup = 12.0 Tbsp = 177.44 mL
- 8.0 fl oz: 1.0 Cup = 16.0 Tbsp = 236.59 mL
- 12.0 fl oz: 1 (1) / (2) Cups = 24.0 Tbsp = 354.88 mL
- 16.0 fl oz: 2.0 Cups = 1.0 Pint = 473.18 mL
- 32.0 fl oz: 4.0 Cups = 1.0 Quart = 946.35 mL
Equations
- US Cups = US Fluid Ounces (fl oz)8
- US Fluid Ounces (fl oz) = US Cups × 8
How to Use This Calculator
Enter your Volume Value to Convert (e.g. 8.0), Measuring Cup Standard — choose from US Customary Cup (8.0 fl oz / 236.59 mL / 16 Tbsp), Metric Cup (250.0 mL / 8.45 fl oz / UK, Canada, Australia), US Legal / Nutrition Cup (240.0 mL / 8.12 fl oz), Kitchen Baking Benchmark — choose from Custom Volume Value, 2.0 fl oz (0.25 Cup / 4 Tbsp / 1/4 Cup), 2.67 fl oz (0.33 Cup / 5.33 Tbsp / 1/3 Cup), and Conversion Direction — choose from Fluid Ounces to Cups (fl oz → cups / divide by 8), Cups to Fluid Ounces (cups → fl oz / multiply by 8). Results update instantly as you type — adjust any value to compare scenarios.

Understanding Your Result
Unit conversion precision: round to the same number of significant figures as your original measurement. Converting 6 feet to meters gives 1.8288 m — but if your measurement was approximate (±1 inch), expressing more than 2 decimal places is false precision. For international trade and technical specifications, SI units (meters, kilograms, liters) are the standard. US customary units (feet, pounds, gallons) differ from Imperial UK units: 1 US gallon = 3.785 L vs. 1 UK gallon = 4.546 L.
