Euclid is a measuring cup designed by Joshua Redstone, an engineer who has prior experience of working for both Google and Facebook. Needless to say, it’s no ordinary measuring cup.
Redstone has a knack for baking. As a result of his growing frustration at not being able to measure small quantities of ingredients as accurately as large amounts in existing measuring cups (not even the conical ones), the idea for Euclid hit him.
According to his campaign on Kickstarter,
Euclid is the first measuring cup to measure small amounts and large amounts with equal accuracy. Since recipes are all about ratios, that consistent accuracy across different amounts is essential. Consistency also improves repeatability - key to refining recipes over time.
Named after the father of Geometry, Euclid of Alexandria, the tapered measuring cup has been built so that for every measurement amount, the ratio of surface area to volume is the same. This solves a very simple problem.
With normal measuring cups, the smaller the amount, the harder it is to measure accurately. Why? The shape. Straight sides magnify errors when measuring lower down in the cup. Some have tried to solve this problem with conical measuring cups, but their results fall short of Euclid’s by up to 60%. Euclid is the only measuring cup with a mathematically optimal, tapered design for consistent accuracy across amounts.
In large measurements, overshooting the amount by a little would typically mean an error of 6%. But in case of traditional cups, as the measured amount gets smaller, this error increases proportionally, going up to as much as 20%. In case of Euclid however, because of its design, the error remains constant and negligible regardless of what amount is being measured.
The shape for Euclid has been granted the US Utility Patent, which extends to any device that measures volume, including laboratory equipment, bar jiggers, and rain gauges.
The Kickstarter Campaign has surpassed its initial goal of $30,000, with only a few days left to go. Redstone has informed that Euclid will be ready for delivery to its backers within 6 months of campaign closing.
