Cooking calculators are useful when you need to scale a recipe or convert between ml, teaspoons, tablespoons and cups.
Oven temperatures are also approximate. Fan ovens, older ovens and gas ovens can vary, so always use judgement and check food is cooked safely.
The recipe scaler is helpful when changing a meal from two servings to four, or when reducing a family recipe for one person.
Reminder: Calculators are estimates only. For quotes, tax, legal, health, building or financial decisions, check official sources or speak to a professional.
