Gravimetric is spelled [grav-uh-me-trik] with the stress on the second syllable. The root word is gravity, which means the force that pulls objects towards each other. Gravimetric is an adjective that describes any measurement that is based on gravity. The word is commonly used in scientific research and engineering disciplines, especially in the field of chemistry. If you are not familiar with this word, it can be challenging to spell, so it is important to practice and use phonetic transcription.
Gravimetric, as defined by its etymology, refers to a method or technique of measurement that involves the determination of weight or mass. The term is derived from the combination of "gravi-" (meaning "weight" in Latin) and "-metric" (pertaining to measurement). Gravimetric measurements rely on the principle that the weight of a substance can be quantitatively indicative of its quantity or concentration.
In the field of chemistry, gravimetric analysis is a quantitative method used to determine the amount of a particular substance in a sample. It involves the accurate measurement of the mass of a substance, either in its original form or after undergoing a chemical reaction or separation process. Gravimetric analysis is often used in analytical chemistry for the identification and quantification of elements and compounds in various samples.
Furthermore, in environmental science and engineering, gravimetric measurements are commonly employed for the assessment of air pollution. Gravimetric samplers are utilized to collect airborne particles on a filter medium, which is then weighed before and after sampling. The mass of the collected particulate matter allows for the determination of pollutant concentrations, aiding in the evaluation and regulation of air quality.
Overall, gravimetric refers to a measurement technique that relies on the determination of weight or mass. It finds applications in various scientific disciplines, including chemistry and environmental science, enabling the accurate analysis and quantification of substances or pollutants.

The word gravimetric is derived from the combination of two Latin roots: gravis meaning heavy and metron meaning measure. In this context, gravis refers to the force of gravity, and metron refers to measurement or measurement device. Thus, gravimetric essentially means related to the measurement of weight or force of gravity.
