Question

who messured the value of gravity by an experiment and what was the value​

Answer 1

$\huge\blue{ANSWER:-}$

Lord Henry Cavendish

In equation form, this is often expressed as follows: The constant of proportionality in this equation is G - the universal gravitation constant. The value of G was not experimentally determined until nearly a century later (1798) by Lord Henry Cavendish using a torsion balance.
