What is the term for body measurements and calculations related to human characteristics?

The correct term that refers to body measurements and calculations related to human characteristics is anthropometry. This term encompasses the quantitative measurement of the human body, including dimensions such as height, weight, and circumferences, which are vital for various applications, including nutrition and health assessments. Anthropometry plays a crucial role in understanding body composition and evaluating health risks associated with various measurements.

While biometrics might seem related, it primarily focuses on the measurement and analysis of people's unique physical characteristics for identification purposes rather than general body measurements. Physiology refers to the science of how the body's systems function, and metrology is the science of measurement in general, including various fields not limited to human characteristics. Therefore, anthropometry is the most accurate term for body measurements specifically related to human characteristics.
