Scale factor: 1.5×
Recipes rarely match the number of people you are actually cooking for. A cake written for four servings is awkward when eight guests show up, and halving a family dinner down to one portion means dividing every measurement in your head. This recipe scaler does the arithmetic for you. Set the original servings, set how many you need, and every ingredient updates to the correct amount instantly.
It works for any unit — grams, cups, tablespoons, millilitres — because it only multiplies the number you give it. The result is rounded to two decimal places so you can weigh it precisely on a kitchen scale. Your recipe stays on your device; nothing is sent anywhere.
