Halachic Measuring Cups

Context of the cups

Due to the absence of standardized measuring tools in earlier times, the Chachamim established various methods for determining correct quantities.

For instance, they used references such as the size of an average olive, an egg, or a dried fig. These measurements have since been the subject of debate in order to determine their equivalents in modern measurement systems.

The Gemorah employs various techniques, such as measuring a revi’is by using a fingerbreadth to estimate the height, length, and breadth of the cup that would contain the required amount.

In recent years, Rabbi Chaim Noeh, among other rabbinic authorities, has codified these measurements according to modern systems.

We have designed our cups based on his measurements. Typically, these measurements are categorized into liquid and solid measurements. While the measurements for both types are generally the same, the terminology differs for liquids and solids. To address this distinction, we have created two separate sets of measurements to provide clarity.

Purpose of the cups

The cups serve an educational purpose by demonstrating the Halachic measurement systems for both liquid and solid substances.

They teach students:

that the Torah utilizes distinct measurement systems for both liquids and solids;
that these systems are based on a primary unit of measurement, with the other units being fractions of it; and
that each cup has a unique name, in addition to being designated for a specific fraction of a larger measurement.

Moreover, these cups are exceptional visual aids for teaching Halacha, as each one is accurately measured to the required size.

Target Market

Teachers & students in Upper Primary, High School, Mesivta or Yeshiva Gedolah.

Objective of the cups

Halachic measurements are fundamental to the study and practice of Halacha, as many mitzvos require specific quantities to be fulfilled.

For example, an esrog must meet a certain size requirement, a bracha achrona necessitates a specific amount of food consumption, and a kiddush cup must contain a designated volume of liquid.

In the study of Halacha, understanding the measurements of various items is essential for grasping laws related to acquisition, trade, and other areas.

It is a visual & tangible educational experience
It is a realistic experience

Classroom Implementation

The cups can be used in Chumash, Mishna, or Gemorah classes as visual aids for learning. They can also serve as standalone lessons, illustrate specific halachos, and function as assessment tools to demonstrate understanding of a halacha.
