Forgive me if I sound scolding, but asking this question is like asking "How many dinner plates are in a ski boat?".You must ask how many sq miles are in a sq km. The units have to be consistent in their meaning.Having said that, if you want to know how many sq mi are in 3,000,000 sq km the the answer is quite simple.~1.6 km/miSquaring this we get 2.56 sq km/sq mi3,000,000 sq km divided by 2.56 sq km/sq mi gives us 1,171,875 sq miTherefore there are approximately 1,171,875 sq mi in 3,000,000 sq km
7 million square meters ------------------------------------------------------------- 1 km = 1,000 m 1 sq km = 1 km × 1 km = 1,000 m × 1,000 m = 1,000,000 sq m → 7 sq km = 7 × 1,000,000 sq m = 7,000,000 sq m.
