What's the formula to convert grams into ounces
Multiply grams by 0.0353 to convert grams into ounces
16120 g = 569.036 oz
Answer = int(16120 * .0353) [569 oz]
The formual for converting ounces to pounds and ounces (rather than decimal fractions)
oz_start = 569
lb_calc = int(oz_start/16) [therefore lb_calc == 35 lb]
oz_calc = 569 - (lb_calc * 16) [therefore oz_calc = 9 oz]
Answer = lb_calc, oz_calc [35 lb, 9 oz]
