<h1>How Many Oz in 1 Cup?</h1>
<h2>Quick Scoop</h2>

<p>Ever stood in the kitchen wondering just how many ounces go into a cup? You're not alone — this is one of the most common cooking and baking questions out there. Let’s clear that up once and for all!</p>

<h3>🧂 The Simple Answer</h3>
<p><strong>1 U.S. cup = 8 fluid ounces (fl oz)</strong> when measuring liquid ingredients like water, milk, or oil.</p>

<h3>📏 But — There’s a Catch!</h3>
<p>When it comes to dry ingredients, ounces measure <em>weight</em>, not volume. That means:</p>
<ul>
  <li><strong>1 cup of all-purpose flour</strong> weighs about <strong>4.5 ounces</strong>.</li>
  <li><strong>1 cup of sugar</strong> is roughly <strong>7 ounces</strong>.</li>
  <li><strong>1 cup of butter</strong> equals <strong>8 ounces (or 2 sticks)</strong>.</li>
</ul>

<h3>💡 Pro Tip: Measuring Smart</h3>
<ol>
  <li>Use <strong>liquid measuring cups</strong> for fluids (they usually have a spout).</li>
  <li>Use <strong>dry measuring cups</strong> and level them off for dry foods.</li>
</ol>

<h3>🌍 Regional Differences</h3>
<p>Be aware that not all “cups” are created equal around the world:</p>
<ul>
  <li><strong>U.S. cup:</strong> 8 fl oz (about 237 mL)</li>
  <li><strong>U.K. cup:</strong> 10 fl oz (284 mL)</li>
  <li><strong>Metric cup:</strong> 250 mL</li>
</ul>

<h3>🍳 In Everyday Cooking</h3>
<p>When a recipe says "1 cup" without specifying dry or liquid, context matters. A cake recipe usually expects <em>dry ingredient ounces</em> by weight; a smoothie recipe assumes <em>liquid ounces</em> by volume.</p>
