It is 1 million sq metres.
1 square km of gravel
1 million.
0.01 km square
Oh, dude, it's simple math time! So, if you have a square with a side of 1 km, the area of that square would be 1 km multiplied by 1 km, which equals 1 square km. It's like, you just multiply the side length by itself to get the area. Easy peasy lemon squeezy!
Square root (1 km^2) = 1 km.
1 square km = 1 million square metres.
1 square mile = 2.59 square km 1 square km = 0.39 square mile
1 square mile = about 2.6 square km (2.58998811 square kilometers).
"1 km" is a distance. It has no area.1 square km = 10,763,910 square feet (rounded)
1 mile = 1.609344 km (exactly) → 1 sq mile = 1 mile × 1 mile = 1.609344 km × 1.609344 km ≈ 2.58999 sq km → To approximately convert square miles to square km multiply by 2.59.
Answer: 1 mi² = 2.58998 km²
Answer: 1 km² = 0.386102 mi²
