    According to SI agreement , g = 9.80665 , therefore :

    weight = m*g = 45*9.80665 = 440 N (just 2 sign. figures)

    Depends on your local value for "g."

    For g = 9.8 m/s², the weight is

    F = m*g = 45kg * 9.8m/s² = 441 N

    which should be rounded to 440 N owing to the number of significant digits in "45 kg".

    Hope this helps!
