What is the weight of an object (on earth) that has a mass of 45 kg?
- oubaasLv 71 month ago
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!
