The person behind the tools
I'm an independent developer and I build small, fast cooking tools. Ingredient Calculator is one of them. Scale a recipe, convert cups to grams, swap an ingredient you ran out of, check rough nutrition. No account, no pop-ups, no life story before the calculator loads.
One job per tool, done fast
Most cooking sites bury a simple converter under ads and a thousand-word essay about someone's grandmother. I go the other way. Each tool does one thing and loads right away.
The cups to grams converter carries a real density for every ingredient, because a cup of flour and a cup of honey weigh nothing alike. The nutrition estimator runs on USDA numbers. The scaler handles the awkward parts of doubling a recipe, like what to do with three eggs when you need four and a half.
I made the whole site on my own and I work on it full time. That's the only reason the tools stay quick and a feature request from a stranger actually gets read the same day.
What works, and what didn't
Not every tool lands. Some I built, watched nobody open, and quietly pulled down. The ones that stay are the ones people come back to.
So I'd rather hear what's broken than guess at it. If a number looks off, or you want an ingredient added, or a tool would save you a step, send it over. Small fixes usually ship the same week, and the bigger ideas go on a list I actually work through.
Keep the tools free, or get all of them
Every calculator here is free and stays free. There's no paywall on the math, and there never will be. Two options if you want more than that.
The paid tools, for good
The only thing sold on this site. You get recipe costing and pricing, a recipe library, batch scaling, printable recipe cards and a merged shopping list, all unlocked at /pro/ by a key. The Kitchen Pack comes with it: five kitchen tools that work with no internet, a printable PDF reference, and the ingredient data as CSV and JSON. One payment covers everything, including future updates.

Tools, code, and a real inbox
IngredientCalculator Pro is sold here, and the Kitchen Pack comes with it. The membership and the rest of what I make live on zovo.one. The code I can share sits on GitHub. Got a question before you spend anything? Email me and a real person, me, writes back.
Try the tools first
The best way to decide if any of this is worth it is to use the thing. Start with the scaler or the converter, then come back if you want the rest.
