Tombola

Tombola is a utility toolkit with a unit converter that covers both volume and weight, making it the ideal companion in the kitchen when recipes use unfamiliar or mixed measurement systems. The volume converter handles teaspoons, tablespoons, cups, fluid ounces, pints, quarts, liters, and milliliters, covering the full range from a pinch of vanilla to a pot of broth. The weight converter handles grams, kilograms, ounces, pounds, and more, perfect for scaling recipes that mix metric and imperial ingredients or adjusting portion sizes. The percentage calculator adds another kitchen skill: calculate how much a recipe scales by percentage, figure out what percent of your daily calorie target a meal represents, or work out a tip on a restaurant bill. Tombola works entirely offline with no account required, the converter and all nine other tools are available immediately without any setup.
