The science and practice of measuring gravitational fields and variations, or a method of chemical analysis based on mass measurements.
From Latin 'gravis' (heavy) and Greek '-metria' (measurement, measuring), combining into the broader scientific field combining gravity study with measurement.
Gravimetry literally helped shape our understanding of Earth's interior—by measuring how gravity varies across the planet, scientists discovered that the Earth's core is much denser than the crust, revolutionizing geology.
