We convert everything to pounds to make it easier.
A pound is approximately 453.59 grams
So 125 pounds of cement is 56,698.75 grams
1 gram is well... 1 gram
60 kilograms is 60,000 grams
6 pounds is obviously less than 125 pound so we don't mind it.
So the 125 pounds of cement weighs the most among the rest
