How do you measure things? Feet, gallons & pounds? Meters, liters and kilograms? Judaism has its own measurement system.

Many rules in Judaism require specific weights, lengths or volumes. Torah includes a full system of measurements for all of Jewish law.  Many of those measurements are based on the human body similar to the 'foot' that we use in the 'US customary system'. To accurately use those measurements today, we need to be certain that humans have not changed in size over time, but have they?

Learn about Jewish measurements and the great debate over whether humans have grown over time.
