I found 2 tables describing raising precision in experiments performed to investigate Equivalence Principle:(adsbygoogle = window.adsbygoogle || []).push({});

http://en.wikipedia.org/wiki/Equivalence_principle#Tests_of_the_weak_equivalence_principle

http://en.wikipedia.org/wiki/Hughesâ€“Drever_experiment#Modern_experiments

I can't understand how to compare the two tables: is that possible? If second one is expressed in GeV, in which unit of measure is the first expressed? Is it just an adimensional ratio?
