In this video, I show how to convert units of area and present the relationships between square millimeters, square centimeters, square decimeters, square meters, square kilometers, as well as additional units – the are and the hectare. Using the area of a square, I explain why conversions between area units involve multiplying or dividing by 100 or its multiples. I discuss the notation of units, derive the conversion factors step by step, perform sample conversion calculations, and solve typical word problems involving converting square meters to ares and hectares.
