Common Baking Conversions

Weight

  • 1 cup all-purpose flour ≈ 125g
  • 1 cup granulated sugar ≈ 200g
  • 1 cup brown sugar ≈ 220g
  • 1 stick butter = 113g
  • 1 large egg ≈ 50g

Volume

  • 1 cup = 237ml = 16 tbsp
  • 1 tbsp = 3 tsp = 15ml
  • 1 fl oz = 30ml = 2 tbsp
  • 1 liter = 4.23 cups
  • 1 gallon = 3.785 liters

Temperature

  • 350°F = 175°C = Gas Mark 4
  • 375°F = 190°C = Gas Mark 5
  • 400°F = 200°C = Gas Mark 6
  • 425°F = 220°C = Gas Mark 7
  • 450°F = 230°C = Gas Mark 8

Pro tip: For accuracy in baking, always prefer weight measurements (grams) over volume measurements (cups).

Why Serious Bakers Insist on Grams (Not Ounces)

As you delve deeper into the world of baking, you'll notice a clear trend: modern, professional recipes almost exclusively use grams (g), while many traditional American recipes use ounces (oz). While both are units of weight, grams offer a higher degree of precision, which is non-negotiable for baking success.

For example, a recipe calling for "0.5 oz of yeast" translates to 14.175 grams. If your scale only measures in full ounces, you could easily add too much or too little, directly impacting your dough's rise. With grams, you can measure to a fraction of a unit, giving you complete control. In baking, which is essentially "kitchen chemistry," precision dictates the outcome.

The Two Faces of the Ounce: Weight (oz) vs. Fluid (fl oz)

A common pitfall for bakers is confusing the avoirdupois ounce (oz), a unit of mass, with the fluid ounce (fl oz), a unit of volume. One cup of water has a volume of 8 fluid ounces, and its weight is also conveniently close to 8.3 ounces. However, one cup of all-purpose flour also has a volume of 8 fluid ounces, but its weight is only about 4.5 ounces. This converter deals strictly with weight ounces (oz) to ensure accuracy.

Quick Conversion Chart for Common Baking Ingredients

While our tool provides precise conversions for any value, understanding the approximate conversions for common ingredients can help you estimate at a glance:

Ingredient 100 Grams (g) is roughly... 1 Ounce (oz) is exactly...
Flour / Sugar / Butter3.53 oz28.35 g
Water / Milk3.53 oz28.35 g
Whole Eggs (~2 large)3.53 oz28.35 g

Pro Tip: You'll notice that weight conversions are linear and consistent, unlike volume conversions (like cups), which vary dramatically based on ingredient density.
