I know everyone but america is all on board with the metric system, but I would suggest, if any can get word to the researchers to start looking at these things in feet and miles.
As there is a lot of encoding in the known pyramids that is apparent when measured in feet.
The old systems of measurement were best, in the past there was the 'megalithic yard' which the ancients used as a measuring system to construct their buildings I'm not a fan of the metric system it doesn't fit into the symbiotic nature of the universe.
