IPA: /ˌɡrævɪˈmɛtri/
KK: /grævɪˈmɛtri/
The process of measuring the strength of gravity or the gravitational field.
Scientists use gravimetry to study changes in the Earth's gravitational field.
Gravimetry is formed from "gravis" (meaning heavy) and "metria" (from Greek "metron", meaning measure). The word refers to the measurement of weight or gravity.
Think of 'heavy' ('gravis') and 'measure' ('metron') to remember that gravimetry is about measuring heaviness or gravity.
