Definition:Standard Gravity

Definition

The standard gravity is a value of the local gravitational constant at the surface of Earth defined by international standard ISO/IEC 80000 as:

\(\ds g_0\)

\(=\)

\(\ds 9 \cdotp 80665\)

$\mathrm {m \, s^{-2} }$

\(\quad\) in SI units

\(\ds \)

\(\approx\)

\(\ds 32 \cdotp 17405\)

$\mathrm {ft \, s^{-2} }$

\(\quad\) in FPS units.

Symbol

The symbol for the standard gravity is $g_0$.

Also known as

The standard gravity is also known as:

the standard gravitational acceleration

the standard acceleration due to gravity

the standard acceleration of free fall.
