# GravitationalConstant

double GravitationalConstant ();

## Purpose

This function returns the value of the gravitational constant. The units are N*M^2/K^2 and the uncertainty is 615 ppm. The gravitational constant is the coefficient of proportionality in Newton's law of gravitation:

Force_Of_Gravity = (Gravitational_Constant * Mass_Of_A * Mass_Of B) / (distance * distance)

## Parameters

None.

## Return Value
