Length of Nippur cubit: 51.84 ± 0.02 cm
    Ratio to Egyptian cubit: 99/100
    Divided into 28 fingers (each finger = 1.8514 cm)
    
    
    Relationship to Other Measurements
    One Roman foot = 24/25 of a Greek foot
    One Roman foot = 35/36 of an English foot
    One small egyptian cubit = 44.45cm = 6/7 of a Nippur cubit
    One Roman foot = 16 fingers = 1.852 x 16 = 29.63 cm
    One Nippur cubit = 28 fingers = 1.852 x 28 = 51.84 cm ±0.02 = 4/7 of one Roman foot
    
    
    Pyramid Measurements in Nippur Cubits
    Great Pyramid base: 440 Egyptian cubits = 444.4 Nippur cubits
    Great Pyramid height: 280 Egyptian cubits = 282.8 Nippur cubits
    
    
    Mathematical Connections
    Pyramid height (282.8 Nippur cubits):
    - √8 = 2.828
    - 200*√2 = 282,8 (the height of the Great Pyramid) = 100*√8
    Base diagonal:
    - 628.43 cubits = 200*π
    Finger measurement:
    - 1/100,000 of a mean meridian minute (99.95% precision)
    
    
    The silver number: 1 + √2
    Some properties:
    1.414 + 1 = 2.414
    1 / 2.414 = 0.414
    1.414 – 1 = 1 / 2.414
    
    
    Using the Nippur cubit as measurement unit, the height of the Great Pyramid measures 200 × the silver ratio, and the diagonal of the pyramid's base measures 200 × π!
    
    The perimeter of the Great Pyramid measures half an arc minute of Earth's meridian with 99.98% accuracy, which is equivalent to the measurement made by Méchain and Delambre at the end of the 18th     century, after 7 years of measurements and 9 years of calculations…
