Bema (unit)
Bema was an ancient Egyptian measure of length and the step , more precisely the mile step . The Romans used this to determine the length of the stadium, for example.
- 1 Bema = 341.33 Paris lines = 0.77 meters
The double bema was considered the geometric step and was five feet (1 F. = 136.49 Parisian lines or 0.3079 meters) or pes long.
A dimensional chain was:
- 1 orgy (about fathoms ) = 2 2/5 bema / step = 4 pechys / cubit = 6 feet = 8 spithame / span = 12 dichas / lichas = 24 palms / hand width = 96 dactylus / finger width = 1,847 meters
