An ex-Google engineer with a passion for cooking created the first and only mathematically optimal measuring cup — and that means better results for every recipe.

Better accuracy.

Euclid’s patented shape makes it the first and only measuring cup to measure small and large amounts with equal accuracy. That’s something no traditional or conical measuring cup can do.
1 Cup 6% 3/4 6% 1/2 6% 1/4 6% Error
Traditional Measuring Cup 1 Cup 6% 3/4 8% 1/2 11% 1/4 20% Error
* error if you overshoot the line by 3mm

Better results.

Recipes are all about ratios, so consistency matters. Euclid’s accuracy across any amount benefits all kinds of cooks, whether you’re a super-careful measurer or your style is pour-and-go.

Innovative shape.

Euclid’s secret is in its patented shape. By maintaining the same ratio of surface area to volume at each measurement line, it keeps accuracy consistent across amounts.

Thoughtful design.

Euclid is made in the USA of BPA-free Tritan plastic. It is durable, dishwasher safe and kid-friendly with its comfortable grip and easy-pour spout. Euclid measures up to 1 cup, 8 fluid ounces or 250 milliliters.
Dimensions: 3.8”L X 4.2”W X 5.3”H
