Question

If a person weighs 320 pounds how much does he weigh in newtons?

Answer 1

320 pound = 1 423.430 921 Newton

Answer 2

A Newton is a person's mass times acceleration due to gravity. Its expanded unit is (kg*m)s^2.

First, convert 320 lbs to kg.

1 pound =  0.45359237 kg

320*.45359237 = 145.149558 kg

On Earth, acceleration due to gravity (g) is 9.8 m/s^2

145.149*9.8 = 1422.46 N

Answer 3

1 pound is 4 newtons

so

1280 newtons
