Description
A c1930 aluminum slide rule for calculating the Harris-Benedict Equation. The Jones Company seemed to specialize in instrumentation for the measurement of metabolism as entering their name in Google will quickly reveal. “The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual’s basal metabolic rate (BMR) and daily kilocalorie requirements. The estimated BMR value is multiplied by a number that corresponds to the individuals’s activity level. The resulting number is the recommended daily kilocalorie intake to maintain current body weight…The Harris–Benedict equation sprang from a study by James Arthur Harris and Francis Gano Benedict, which was published in 1919 by the Carnegie Institution of Washington in the monograph A Biometric Study Of Basal Metabolism In Man.”Wiki
