Before you use the answer
Write the batch size and measurement basis beside the formula before scaling. A weight ratio is not a volume ratio, and a flour-based percentage is not a share of total dough. Record the finished yield so the next batch can be planned from your own measurements.
Brew water is not the same as final beverage mass because grounds retain water.

Why might a result be approximate?
Measurement uncertainty, ideal-model assumptions and floating-point rounding can all matter. Displaying more digits does not improve the original measurement.
