The Universal Gravitational Constant is 6.67384x10-11 (N • m²)/(kg²) or  6.67384•10-¹¹ (m³)/(kg•s²).

#### The Math / Science

The Newtonian constant of gravitation denoted by letter G, is an empirical physical constant involved in the calculation(s) of gravitational force between two bodies . It usually appears in Sir Isaac Newton's law of universal gravitation, and in Albert Einstein's theory of general relativity. The constant is expressed in SI units, Newton meters squared per kilogram per second squared.

#### Application

The Force of Gravity is a function of the mass of two objects (e.g. you and the Earth) and the distance between them. The gravity from the mass of the Earth is pulling on the mass in you and on any other object near the Earth. The formula for the the Force of Gravity is:

where:

• G is the universal gravity constant
• m1 is the mass of the first object
• m2 is the mass of the second object
• D is the distance between them.

The Mass of the Earth is 5.97219x1024 kilograms.  That's:

• 5,972,190,000,000,000,000,000,000.0 kilograms
• 0.00314657 Jupiter Masses
• 0.000003 Solar Masses
