What is a Square Kilometer?
The square kilometer equals one million square meters and is used for measuring the area of countries, cities, lakes, and other large geographic features. Equal to 100 hectares or approximately 0.386 square miles, it is the standard for national land areas and large-scale maps. Russia, the world's largest country, spans approximately 17.1 million km². A key fact: 1 km² equals 1,000,000 m² — not 1,000 — because area scales as the square of length.
What is a Square Inch?
The square inch is an imperial unit equal to the area of a 1 × 1 inch square, approximately 6.452 square centimeters. It is used in the US for paper and fabric dimensions, display resolution measurements (pixels per square inch), and small component specifications. One square inch equals exactly 1/144 of a square foot. Screen resolution is often described in pixels per square inch (PPI).
