Steven goes to the grocery store and is looking at a winter squash. it has a mass of 1.8 kilograms. how many milligrams is the winter squash?

Ok so think about this ( not trying to be rude ) if a kilo = 1000 grams and a gram = 1000 milligrams then there would be 1000000 milligrams in winter squash how I got the solution is by multiplying milligram 1000 to get to a gram then multiply by 1,000 again then do 1,000 times 1,000 then you would get 1000000.

I'm just guessing, but my answer would c. 0 to 300.
