The term "gravimetry" is composed of two words - the Latin word gravitas = gravity and the Greek word τὸ μέτρον = dimension/measurement - and means "gravity measurement".

Gravimetry is of importance for geodesy, geophysics and geodynamics as well as for space missions.
- Geodesy: height and geoid determination
- Geophysics and Geodynamics: research of the interior of the Earth and its movements, mass displacements inside the Earth's body and deformations of its surface, density models of the Earth, exploration of natural resources
- Space missions: orbit determination of spacecraft and satellites
Gravity determination obtained by satellite observations is assigned to satellite geodesy.
