Quick serving size tips for meal prep
\n
Weigh the full cooked batch once, subtract the container weight if needed, then divide by the number of meals you actually plan to eat. That gives you a cleaner serving size estimate than eyeballing portions into containers.
\n
If you also need to switch between grams, ounces, cups, and ingredient-based weights, use the Kitchen Scale Converter right after this tool.
