Of all of the functions they included in L4 and L5, they left out a very important one – Weights and Measures. How are we supposed to understand how far 1500 stades would be or how large a quantity an ephah would constitute without a way to convert to modern measurements. The metric system may be easier in some respects, but, when it comes to understanding the practical significance of their measurements, I have to convert kilometers to miles, liters to gallons and degrees Celsius to degrees Fahrenheit or they mean nothing. It is the same with biblical weights and measures.
