Larderkin: Cups to Grams

A cup of flour and a cup of honey are not the same weight — 120 g against 340 g. Every generic unit converter gets this wrong, because it converts volume to volume and weight to weight and never crosses the line. Larderkin crosses it, because it knows what is in the cup.

WHAT IT DOES

• Cups, tablespoons, teaspoons, millilitres and fluid ounces → grams, kilograms, ounces or pounds, for 68 real ingredients.
• The same conversion backwards: type 200 g and get the cups, right down to "¾ cup" instead of 0.7489.
• A common-measures table on every ingredient — 1 cup, ¾, ⅔, ½, ⅓, ¼, 1 tbsp, 1 tsp — so the answer is on screen before you type anything.
• Batch buttons: ×½, ×1, ×1½, ×2, ×3 for halving or doubling a recipe.
• Oven temperatures: °C, °F, gas mark and fan, plus the nearest standard setting — because 350 °F is exactly 176.7 °C and no oven dial has 176.7 on it.
• Tin sizes: swap a 20 cm round for a 23 cm round and get the multiplier for every ingredient. It scales by base area, not by width, so the batter ends up the right depth.

WHAT IS IN THE LARDER

Flours and starches, sugars and syrups, dairy and eggs, fats and liquids, grains, rice and pasta, nuts, seeds and dried fruit, leaveners, salt and spices. Bread flour, cake flour, almond flour, cocoa, icing sugar, brown sugar, honey, maple syrup, butter, cream cheese, grated parmesan, rolled oats, quinoa, peanut butter, chocolate chips, instant yeast, baking powder, table salt, kosher salt — with the teaspoon weights that actually matter for the small ones.

US OR METRIC, YOUR CHOICE

A US cup is 236.6 ml. A metric cup is 250 ml. The same "1 cup flour" differs by about 7 g between them. One switch in Settings changes every reading in the app, and the current standard is printed at the top of the screen so you always know which one you are reading.

HONEST ABOUT THE NUMBERS

Flour weights assume the spooned-and-levelled method — scooping straight from the bag packs in up to 20% more, and the app says so on the ingredient. Every screen shows the grams per cup and the density it was derived from, so you can check the figure against your own scales instead of trusting a black box.

NO PERMISSIONS, NO ACCOUNT, NO ADS

Larderkin requests zero Android permissions. INTERNET is deliberately absent, so the operating system itself prevents this app from making any network connection — that is enforced by Android, not by our good intentions. There is no sign-in, no ads, no analytics, no third-party SDKs and no tracking of any kind. Nothing you type leaves your phone, because there is no way out.

The only thing stored is your handful of settings and the ingredients you pinned. Cloud backup and device-to-device transfer are both switched off, so uninstalling the app deletes that for good — there is no cloud copy to restore, by design.

WORKS WITH NO SIGNAL

Everything is in the app. The ingredient table, the oven chart, the tin areas and the privacy policy all work in a basement kitchen with no bars, on a plane, or with mobile data switched off forever.
