A unit converter that is actually fast, and knows what things weigh. 13 categories, 124 units, and a real ingredient table: 112 foods with their proper densities, so a cup of flour and a cup of honey do not come out the same. No account, no sign-up, no waiting on a network. WHAT IT CONVERTS - Length, weight, temperature, volume, area, speed, time - Data, pressure, force, energy, power - Cooking, with grams, cups, tablespoons, teaspoons, millilitres and fluid ounces - Every result at once, so you do not pick the target unit before you can see the answer INGREDIENTS THAT WEIGH WHAT THEY WEIGH Flours, sugars, dairy and fats, liquids, nuts, grains, chocolate and fruit, each with real grams-per-cup. This is the part most converters get wrong. YOUR OWN INGREDIENTS No built-in table can know the specific flour you buy, your protein powder, or the starter in your fridge. Weigh one cup of it once, type the grams, and every conversion using it is right from then on. Free keeps three. CONVERTLY PRO - As many of your own ingredients as you want - Your full conversion history instead of the last 10 Converting is free and stays free. Favourites are unlimited and free.
