Ounces to Grams Converter

Converting Ounces to Grams for Cooking

Whether you're following an American recipe with a metric scale or converting international recipes, knowing how to convert ounces to grams is essential for accurate cooking and baking. One ounce equals 28.3495 grams, though most cooks round to 28 or 30 grams for convenience.

Quick Conversion Chart

• 1 oz = 28 g
• 2 oz = 57 g
• 4 oz (1/4 lb) = 113 g
• 8 oz (1/2 lb) = 227 g
• 12 oz (3/4 lb) = 340 g
• 16 oz (1 lb) = 454 g
• 32 oz (2 lb) = 907 g

Common Ingredients

Meat and Protein

• 4 oz chicken breast = 113 g
• 8 oz steak = 227 g
• 12 oz pork chop = 340 g
• 16 oz ground beef = 454 g

Cheese

• 2 oz shredded cheese = 57 g
• 4 oz cream cheese = 113 g
• 8 oz mozzarella = 227 g

Butter

• 1 oz butter = 28 g (2 tablespoons)
• 4 oz butter = 113 g (1 stick)
• 8 oz butter = 227 g (2 sticks)

Chocolate

• 2 oz chocolate = 57 g
• 4 oz chocolate = 113 g
• 8 oz chocolate = 227 g

Weight vs Volume

Weight ounces (oz): Measure mass - what this calculator converts

Fluid ounces (fl oz): Measure volume - different measurement entirely

Example: 8 fluid ounces of water weighs exactly 8 weight ounces, but 8 fluid ounces of honey weighs about 12 weight ounces because honey is denser than water.

Why Use Grams?

1. More precise: Grams are smaller units, allowing finer measurements
2. International standard: Most of the world uses metric system
3. Digital scales: Modern kitchen scales display grams as default
4. Baking accuracy: Professional bakers always use grams
5. No conversion needed: Many recipes list both measurements

Kitchen Scale Basics

Choosing a Scale

• Capacity: At least 5 lbs (2.3 kg) for versatility
• Precision: 1-gram increments ideal for baking
• Tare function: Essential - zeros out bowl weight
• Display: Easy to read, backlit preferred
• Price: Good scales cost $20-40

Using Your Scale

1. Place bowl on scale
2. Press "tare" or "zero" button
3. Add ingredient until desired weight
4. Tare again for next ingredient in same bowl

Tips for Accurate Measurement

• Place scale on flat, stable surface
• Ensure scale is at room temperature
• Replace batteries when readings seem off
• Calibrate periodically with known weights
• Keep scale clean and dry

Converting Recipes

When converting American recipes to metric:

1. Convert all weight measurements to grams
2. Keep volume measurements (cups, tablespoons) for liquids
3. Convert oven temperatures to Celsius
4. Test recipe once, note any adjustments

Common Recipe Weights

Baking

• Flour: 1 cup ≈ 125g (4.4 oz)
• Sugar: 1 cup ≈ 200g (7 oz)
• Butter: 1 stick = 113g (4 oz)
• Eggs: 1 large ≈ 50g (1.8 oz)

Produce

• Medium apple: 6 oz (170g)
• Medium potato: 7 oz (200g)
• Medium onion: 5 oz (140g)
• Medium tomato: 4 oz (113g)

Professional Baking Standards

Professional bakeries use baker's percentages where flour is always 100% and other ingredients are percentages of flour weight. For example:

• Flour: 1000g (100%)
• Water: 600g (60%)
• Salt: 20g (2%)
• Yeast: 10g (1%)

This system scales recipes perfectly to any size.

Digital vs Mechanical Scales

Digital Scales:

• Pros: Precise, easy to read, tare function, affordable
• Cons: Require batteries, can malfunction with moisture

Mechanical Scales:

• Pros: No batteries, durable, vintage aesthetic
• Cons: Less precise, harder to read, no tare function

Troubleshooting Scale Issues

• Inconsistent readings: Replace batteries, clean scale
• Won't zero: Remove all weight, press tare
• Maxed out: Reduce bowl size or weigh in batches
• Reading fluctuates: Place on stable surface, away from vibrations
