Kitchen math for home cooks and bakers: scale recipes by servings, convert tsp/tbsp/cups and grams, swap oven °F and °C, convert yeast types, butter sticks to grams, baker’s percentages, pasta portions, turkey thaw times, and air-fryer temperature/time adjustments. Estimates only — follow package directions and food-safety guidance for meat and poultry.
