Practical Tools for Cooking and Driving
From scaling a recipe for a dinner party to calculating how much a road trip will cost in fuel, these 8 free tools handle the practical calculations that come up in everyday life.
Cooking Tools
The Recipe Scaler multiplies or divides all ingredient quantities by a single factor — perfect for cooking for a crowd or halving a batch. The Cooking Unit Converter switches between cups, tablespoons, teaspoons, millilitres, fluid ounces, and more. The Oven Temperature Converter translates between Celsius, Fahrenheit, and gas mark settings so you can follow any recipe regardless of your oven's display. The Nutritional Calorie Calculator estimates the calorie content of common ingredients by weight.
Automotive Tools
The Fuel Efficiency Calculator converts between miles per gallon, litres per 100 km, and km per litre — useful when driving in a country that uses different units. The Fuel Cost Calculator estimates the total fuel cost for a journey given distance, fuel price, and efficiency. The Tire Size Calculator decodes tire specifications (e.g. 205/55R16) and compares two tire sizes for diameter, sidewall height, and speedometer accuracy. The Speed Distance Time Calculator solves for whichever variable you need — average speed, total distance, or travel time — given the other two.
