Using Random and Range together

I would like to utilise random and range together in this code. Im trying to figure how the user can input a weight unit (kg or pounds) and the output would be a range of weights between 10 and 200, and only generate say 100 random weights between that range. I think its only a small fix, I just can't nut it out where it should go.

Code so far..

import random

weight_unit = input("Enter the units: , kg or pounds")

while weight_unit != 'pounds' or weight_unit != 'kg':
    
if weight_unit =='pounds':
        for i in range(10,200):
            print("weight_unit" , i+1, '=', i,'pounds')
        break
    
    elif weight_unit == 'kg':
        for i in range(10,200):
            print("weight_unit ", i+1, "=" ,round(i/2.204,2),"kg")
        break
        
    else :
        weight_unit = input("Incorrect input. Reinput the unit kg or pounds")
