Biblical

Israelites initially followed Babylonian system of units, but the units were later altered. There were royal and common versions of units and each of these forms had heavy and light versions. Gradually the system reformed again under the Egyptian influence. For example a shekel (silver coin) could weigh anything between 8 and 16 grams in various places and periods of history. That's why it is impossible get an exact conversion from biblical units to contemporary ones.
