A rough guide when you are measuring liquids: 1 ml of water equals 1 gram, 1 litre of water weighs approx 1 kilo - other liquids may differ.
This is the formula to convert grams into ounces
Grams X 0.0353 equals ounces
92 g = 3.2476 oz
Answer = int(92 * .0353) [3 oz]
This is how to calculate ounces to pounds and ounces (rather than decimal fractions of a pound)
oz_start = 3
lb_calc = int(oz_start/16) [therefore lb_calc == 0 lb]
oz_calc = 3 - (lb_calc * 16) [therefore oz_calc = 3 oz]
Answer = lb_calc, oz_calc [0 lb, 3 oz]
