If 1 kilogram = 2.206 pounds, how many pounds are in a gram?

Kaylis [27]

$First:\\1kg\approx2.206lb?\ I\ think,\ and\ I know:1kg\approx2.205lb !!!\ Not\ 2.206lb\\------------------------------\\1kg=1000g\to1g=\frac{1}{1000}kg=0.001kg\\therefore\\1g\approx\frac{2.206}{1,000}lb=\boxed{0.00226\ lb}\\\\in\ My\ correct\ rounding:\\\\1g\approx\frac{2.206}{1,000}lb=\boxed{0.00225\ lb}$
