In the English system (also known as the Imperial system or US customary units), we primarily use ounces, pounds, and tons to measure mass and weight. While technically different, in everyday use on Earth, these units are often used interchangeably to describe how "heavy" something is.

Here's how these units relate to each other:

Here are the primary units you'll encounter and their relationships:

• Inch (in): This is the smallest common unit, often used for smaller objects like paper or a book.
• Foot (ft): A foot is made up of 12 inches. This is a very common unit for everyday measurements like height or room dimensions.
• Yard (yd): A yard is equal to 3 feet. It's often used for fabric, sports fields, or shorter outdoor distances.
• Mile (mi): A mile is the largest common unit, used for long distances like travel between cities. A mile is significantly larger than a yard.

When we talk about volume, we're often dealing with cubic units. Imagine a cube where each side is 1 inch long; that's 1 cubic inch (in³). If each side is 1 foot long, it's 1 cubic foot (ft³).

Capacity, on the other hand, often uses specific liquid measures. You're probably familiar with things like a pint of ice cream or a gallon of milk. These units have specific relationships to each other.

Area and volume are fundamental measurements in everyday life. We use them to figure out how much carpet we need, how much water a pool holds, or even how much space a refrigerator takes up.

• Rectangle/Square: To find the area, you multiply its length by its width.
  Area = Length × Width
• Circle: The area of a circle depends on its radius (the distance from the center to the edge). You use the constant Pi (approximately 3.14159).
  Area = π × Radius²
• Triangle: A triangle's area is half of its base multiplied by its height.
  Area = ½ × Base × Height
