Answer :

To convert kilograms to grams, you use the conversion factor that 1 kilogram is equal to 1000 grams.

Here’s the step-by-step process:

1. Identify the given weight in kilograms: You are given 4 kilograms.

2. Know the conversion factor: 1 kilogram = 1000 grams.

3. Multiply the weight in kilograms by the conversion factor:
[tex]\[ \text{Weight in grams} = \text{Weight in kilograms} \times 1000 \][/tex]
So,
[tex]\[ 4 \, \text{kg} \times 1000 \, \text{g/kg} = 4000 \, \text{grams} \][/tex]

Therefore, 4 kilograms is equal to 4000 grams.
