Why I Built Tell Me in Grams

The Kitchen-Table Realisation: Healthy Eating Meets "Cups"

A few years ago, I started getting much more serious about cooking at home and healthy eating. Like many people focused on nutrition, portion awareness, and consistent cooking, I invested in a good set of digital kitchen scales. Once you start weighing your ingredients, it quickly becomes second nature: it’s cleaner, there are fewer dishes to wash, and you know exactly what is going into your food.

The problem started when I looked for new recipes online. A huge portion of the best cooking and baking content on the web uses US volumetric measurements. Suddenly, instead of clean gram weights, I was confronted with "1 cup of Greek yogurt", "half a cup of rolled oats", or "3/4 cup of chopped nuts".

Volumetric measuring is inherently frustrating when you already have an accurate scale sitting right on the counter. Why dig measuring cups out of a drawer, get them sticky with peanut butter or honey, and then try to scrape them clean, when you could simply place your bowl on the scale and pour?

The Frustration with Existing Solutions: 500-Row Tables and PDFs

Naturally, my immediate instinct was to Google the conversion: "1 cup of oats in grams".

What I found was almost comical. Most existing conversion pages fell into one of two extremes:

• The Endless Monster Table: Giant, single-page articles containing 500 rows of unsearchable text that took forever to load on mobile while I was standing over a mixing bowl with messy hands.
• The Downloadable PDF: Sites that actually required downloading a multi-page PDF chart just to find out what half a cup of flour weighed.

As someone who works in web engineering and product management in fintech, I knew the web could do so much better. I wanted a site with simple HTML that loads instantly, gives you the exact answer immediately at the very top, and provides an interactive calculator if you need an unusual fraction.

So, I decided to build it.

Why Accuracy & Density Matter

A common mistake made by generic converters is assuming that all cups can be multiplied by water’s volume (236.6 ml ≈ 240g). In reality, culinary ingredients have wildly different densities and packing properties:

• A cup of flour fluffed and spooned weighs 120g to 125g. If scooped directly from the bag, it compacts to 140g+.
• A cup of dense Greek yogurt weighs 245g.
• A cup of airy cocoa powder weighs just 86g.

That is why every ingredient on Tell Me in Grams is cross-referenced against authoritative scientific and baking benchmarks—specifically the USDA FoodData Central database and King Arthur Baking’s Master Weight Chart. We also document specific measurement techniques (like spooned vs. scooped) so your recipes turn out exactly as the author intended.
