Use this calculation to scale a recipe or express ingredient quantities relative to a defined base amount while preserving the intended proportions.

Water (g)

Total water weight in the dough.

Flour (g)

Total flour weight in the dough.

Calculate baker's hydration as the water weight expressed as a percentage of flour weight. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Hydration (%)

Water weight as a percentage of flour weight.

• Linear scaling does not guarantee identical cooking behavior. Pan geometry, mixing, proofing, evaporation, heat transfer, ingredient variability, and practical rounding can change texture, timing, and yield.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Scale critical ingredients by mass, then adjust vessel size and cooking time separately. Record the tested yield and revise hydration or seasoning after a small trial when precision matters.

• Recipe Scale Calculator

  Scale an ingredient amount from one serving count to another proportionally.

• Percentage Points Calculator

  Calculate the difference between two percentages expressed in percentage points.

• Water Cement Ratio Water

  Calculate mixing-water mass from cement mass and a water-to-cement mass ratio; account for aggregate moisture separately.
