How do you convert 721 lbs per week into kg per second?
Well, first of all, "pound" is a unit of force, while "kilogram" is a unit of mass,and neither one can be coverted to the other one, even though people arealways doing it.But in order to answer your question, we'll close our eyes, hold our nose, andsay that a kilogram of mass is 'equal' to its weight on Earth ... 2.20462 pounds.(721 pound/wk) x (1 kg/2.20462 pound) x (1 wk/7 da) x (1 da/86,400 sec) = 0.0005407 kg/sec (rounded)
