lb equals 890 mg - 5400 mg kg


  • Simple DA method for 10 mg drug
`(10 \quad mg)/(1\quad kg) × 197 \quad lb × (0.454\quad kg)/(1\quad lb)` = 894.38 mg


  • Simple DA method for 60 mg drug
`(60 \quad mg)/(1\quad kg) × 197 \quad lb × (0.454\quad kg)/(1\quad lb)` = 5366.28 mg


Therefore, range is from 894.38 mg to 5366.28 mg actually, literatures round these numbers and express as 890 mg to 5400 mg
