How do you convert 721 lbs per week into kg per second?

Answer 1

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 are

always doing it.

But in order to answer your question, we'll close our eyes, hold our nose, and

say 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)

Answer 2

1 day = 86,400 seconds

1 week = 7 days = (7 x 86,400) = 604,800 seconds

Assuming this problem takes place on the earth, 1 kg weighs 2.20462 pounds (rounded).

1 pound per week = (1/2.20462) / (604,800) = 7.5 x 10-7 = 0.00000075 kg/sec

Answer 3

721 pounds per week = 721*0.45359 = 327.04 kg per week= 327.04/7 = 46.72 kg/day

= 46.72/24 = 1.9467 kg/hour

= 1.9467/60 = 0.0324 kg/min

= 0.0324/60 = 0.00054 kg/sec.

Answer 4

721 pounds per week equates to 0.000540741 kg per second.
