Standard Gravitational Parameter

The Standard Gravitational Parameter calculator computes the Standard Gravitational Parameter for a body based on the mass of the body (M) and the Universal Gravity Constant (G).

INSTRUCTIONS: Choose units and enter the following:

• (M) This is the mass of the body

Standard Gravitational Parameter (μ):  The calculator return the parameter in m³/s².

The Math / Science

The formula for the Standard Gravitational Parameter is:

        μ = M•G

where:

• μ is the Standard Gravitational Parameter for a body
• M is the mass of the body
• G is the  Universal Gravity Constant.

The Standard Gravitational Parameter is used in celestial mechanics for the prediction of a smaller body about the main body of mass.
