Baking Measurement Converter
Convert common sourdough ingredients between volume and weight so your formulas stay accurate. Use it when a recipe gives cups but you want grams, or grams but you need quick kitchen volume conversions.
How to Use This Converter
- Select your ingredient.
- Choose conversion direction (volume to weight or weight to volume).
- Enter your amount and unit.
- Use the result plus alternate units for quick scaling.

Frequently Asked Questions
Why do cup measurements vary so much?
Cup measurements change with technique. Scooped flour can be 10-15% heavier than spooned-and-levelled flour, which is why gram-based baking is more consistent.
Is 1 cup of flour always 120g?
Not always. 120g is a practical average for spooned all-purpose flour. Bread flour, whole wheat, and rye can differ, and packing method changes the result.
Should I use volume or weight for sourdough baking?
Use weight whenever possible. Sourdough depends on precise flour and water ratios, and grams remove the variability that cups introduce.
Can I convert from grams back to cups accurately?
Yes, as a useful estimate. Weight-to-volume conversions are best treated as practical kitchen guidance, not lab precision.
Do ingredient densities change by brand?
They can. Protein level, grind size, moisture, and how finely ingredients are milled can shift weight-per-cup values.
How should I measure flour if I do not have a scale?
Spoon flour into the cup and level it with a straight edge. Do not scoop directly from the bag, which compacts flour and over-measures.
Why does salt conversion differ between fine and kosher salt?
Crystal shape and size are different. A tablespoon of fine sea salt weighs much more than the same tablespoon of Diamond kosher salt.
Are these values for US cups or metric cups?
These references use US cup measurements. If you use metric cups, values may differ slightly.
