Step-by-step explanation:

Answer:

6,450 g

Step-by-step explanation:

Since there are 1000 grams in 1 kilogram, you multiply 6.45 kg x 1000 g.

6.45 x 1000 g equals 6,450 grams. Move the decimal 3 times to the right because there are 3 zeroes in 1000.

You always move your decimal to the right when multiplying decimals.
