Based on watts produced and body surface area Still another definition of 1 MET is 58.2 W/ m2 (18.4 Btu/h·ft2), which is equal to the rate of energy produced per unit surface area of an average person seated at rest. The surface area of an average person is 1.8 m2 (19 ft2). Metabolic rate is usually expressed in terms of unit area of the total body surface (ANSI/ASHRAE Standard 55ANSI/ASHRAE Standard 55, Thermal Environmental Conditions for Human Occupancy).
Based on watts produced and body surface area Still another definition is based on the body surface area, BSA, and energy itself, where the BSA is expressed in m2 : which is equal to the rate of energy produced per unit surface area of an average person seated at rest. The BSA of an average person is 1.8 m2 (19 ft2). Metabolic rate is usually expressed in terms of unit area of the total body surface (ANSI/ASHRAE Standard 55ANSI/ASHRAE Standard 55, Thermal Environmental Conditions for Human Occupancy).
