You do not. A gram is a measure of mass, whereas a centimetre is a measure of length. The two measure different things and, according to the basic principles of dimensional analysis, conversion from one to the other is not valid.
It is: 2000g+250g = 2250 grammes
250g = 1/4kg
To determine how many 250g bags are in 2 kg, we need to convert the weight to the same unit. Since 1 kg is equal to 1000g, 2 kg is equal to 2000g. To find the number of 250g bags in 2000g, we divide 2000g by 250g, which equals 8. Therefore, there are 8 bags of 250g each in 2 kg.
250 g
It is 2.15
