I am working a problem and I have to make the following units dimensionless: 11.38g/day * 2.82ug/kg * 17.5kg-day/mg/ 20kg

17 years ago

(g/day)*(ug/kg)*(kg.day/mg)/ kg

17 years ago

(11.38 g/day)*(2.82ug/kg)*(17.5kg-day/mg)/20kg = 0.000000002808015 What would be the symbols after the number g/kg, ug/kg? I have no clue Please help

17 years ago

(11.38 g/day)*(2.82ug/kg)*(17.5kg-day/mg)/20kg Just looking at the numbers: 11.38 * 2.82*17.5/20 =561.603/20 =28.08015 But what should I have as the extension g/kg or what?
