General Conversion Formulas
When you don't have a specific chart handy:
- Ounces to grams: Multiply by 28.35
- Grams to ounces: Divide by 28.35
- Pounds to grams: Multiply by 453.6
- Grams to pounds: Divide by 453.6
Quick Estimates
- 1 oz ≈ 30 g (actually 28.35 g)
- 100 g ≈ 3.5 oz
- 1 lb ≈ 450 g (actually 454 g)
- 1 kg ≈ 2.2 lb
Tips for Accurate Measuring
Measuring Flour
- Fluff the flour in the container with a fork
- Spoon flour into the measuring cup (don't scoop)
- Level off with a straight edge
Or better yet: use a kitchen scale!
Measuring Sticky Ingredients
For honey, molasses, or peanut butter, spray the measuring cup with cooking spray first—the ingredient will slide right out.
Investing in a Kitchen Scale
A digital kitchen scale costs around $15-25 and will improve your baking dramatically. Look for one that:
- Switches between grams and ounces
- Has a tare (zero) function
- Measures in 1-gram increments
Conclusion
Whether you're scaling a recipe, following international instructions, or improving your baking precision, understanding kitchen weight conversions is an essential skill. Keep this guide bookmarked, or better yet, invest in a kitchen scale and measure by weight for consistent results every time.
