The value of the gravitational constant (big G) is only known with certainty to the second decimal place. I think the third decimal place is known with some confidence but beyond that there is little agreement among the 200 or so experiments which have measured its value. This an embarrasment when compared with the level of precision and accuracy which other constants are known.
