Target dough temperature °C

Kitchen °C

Flour °C

Friction factor about 4 by hand, 13 in a mixer

Preferment's temperature °C — optional

Water the recipe needs g

Your tap °C

Your hot water °C

Enter your kitchen's temperatures, then press Calculate.

From the book — Chapter 6. Water = 3 × target − kitchen − flour − friction. With a preferment it is 4 × target, and you subtract its temperature too. Measure your own friction factor: 3 × the dough's real temperature, minus the other three.

All in degrees Celsius. A friction factor is a difference, so it converts from Fahrenheit by ÷ 1.8 with no 32. Everything stays in your browser — no sign-up, nothing stored.
