How many square meters in a square kilometer?

Answer 1

There are one million (1,000,000, 1 x 106) square meters in a square kilometer.

There are 1000 meters in 1 kilometer. Thus to get the number of square meters in 1 square kilometer, you must square the number of meters in a kilometer. 1,000 meters X 1,000 meters = 1,000,000 square meters.
Is it one million, e.g. 1000 x 1000?
