Convert weight ounces, not fluid ounces, into grams for cooking recipes. Match the units and baseline before calculating, then record the result so the same conditions can be compared later.
The result is a starting point. Adjust in small steps when ingredient brands, containers, equipment power, or starting temperature differ, and prioritize official guidance for safety-critical work.
