Your cup of flour
is not the chart's
cup of flour
Every calculator on this page is free and stays free. The Kitchen Pack is the offline half of the site. Ten pages built to print, five single file tools that run with the wifi off, and a converter that asks you to weigh one level cup of your own flour and then follows your number instead of a published average.
Cup weights for 35 ingredients
At every common fraction, 245 figures, each row carrying the range its sources actually publish.
A converter that calibrates to your own cup
It takes about ninety seconds. No other cups to grams reference found in four rounds of competitor research to August 2026 asks you to do it.
Oven temperatures in one grid
Fahrenheit, dial Celsius, exact Celsius, gas mark and fan, plus twelve tin areas and 144 swap multipliers.
The corrections that are not multiplication
Leavener, thickener and salt, at 75 and 70 percent, both cited to the source they came from.
The arithmetic
no recipe
ever shows you.
Doubling a family recipe, halving a sheet of cookies, or turning a European bake into something your imperial measuring cups can handle. The math is fiddly. We do it so you don't have to.
Up, down, sideways
Parses fractions, decimals, and unicode glyphs. Returns readable fractions back.
Cups ⇄ grams ⇄ °C
Volume, weight, and temperature, with a quick-reference for the things you forget at 7 am.
For when you're out
17 staple ingredients, several swaps each, with ratios and editor notes on which is which.
Quick macro math
USDA per-100g averages for 25+ ingredients. A sanity-check, not a meal plan.
A cup is
not a cup.
Volume measurements lie. The same cup holds anywhere from 90 grams of rolled oats to 340 grams of honey, almost four times the weight. It's why your grandmother's recipe never tastes the same twice, and why bakeries weigh.
