## Homework Statement

What are the magnitud of G (gravitational constant) and the age of the solar system in CGS system of units and in seconds respectively? and what is the precision of these values and why?

## Homework Equations

## The Attempt at a Solution

I found that the value of G in CGS system is 6.674 X 10

^{-8}cm

^{3}g

^{-1}s

^{-2}(approximately) and the age of the solar system is 4600 million years and in secons is : 1.450656 X 10

^{17}seconds (approximately)

So my question is: what is the precision of these values? and why? do I need to put the uncertainities? I also found that the gravitational constant has a precision of 1 over 10,000 but why? so I really would appreciate your help :)
