Square kilometre facts for kids
A square kilometer (often written as km²) is a way to measure area. It's part of the SI system, which is used worldwide. Think of it as the space inside a square shape where each side is exactly 1 kilometer long. Since 1 kilometer is 1000 meters, a square kilometer is a very large area!
People often use square kilometers to describe the size of land. For example, you might hear it used for the area of a country, a city, or even a very large park. It helps us understand how much space something covers.
To give you an idea, one square kilometer is a bit less than 0.39 square miles.

What is a Square Kilometer?
A square kilometer is a unit of measurement for area. It tells you how much flat space something takes up. Imagine a giant square drawn on the ground. If each side of that square is 1,000 meters (or 1 kilometer) long, the space inside it is one square kilometer.
Why Do We Use Square Kilometers?
We use square kilometers to measure large areas of land. It's much easier than using square meters for big places. For instance, it's simpler to say a city is 100 square kilometers than 100,000,000 square meters! It helps scientists, geographers, and city planners describe land sizes clearly.
How Big is a Square Kilometer?
To help you picture it, a square kilometer is roughly the size of:
- About 140 standard football fields.
- A square with sides that are each about 0.62 miles long.
- A large park or a small town.
