Organ and tissue coefficients used in developing models

Residual*23.1645.650

Weight, density, and potassium were derived from 70-kg Reference Man (48); metabolic rate was derived from Elia (8).

↵* Residual mass was not assigned a density but was calculated as body mass minus sum of other measured mass components.




※cf.

1(kcal)＝4.184(kJ)

4.184(kJ)=1(kcal)

1(kJ)=1÷4.184(kcal)

55(kJ)=55÷4.184(kcal)

55(kJ ⋅ kg−1 ⋅ day−1)=55÷4.184(kcal ⋅ kg−1 ⋅ day−1)

55(kJ ⋅ kg−1 ⋅ day−1)=13.1453154875(kcal ⋅ kg−1 ⋅ day−1)

55(kJ ⋅ kg−1 ⋅ day−1)≒13(kcal ⋅ kg−1 ⋅ day−1)

55(kJ/kg/day)≒13(kcal/kg/day)

55(kJ/kg・day)≒13(kcal/kg・day)
