How the territory calculator works

This calculator computes the area and perimeter of a piece of land based on its shape and dimensions. Choose from rectangle, square, circle, or triangle — then enter your measurements. The tool automatically converts the area into acres, hectares, square feet, square metres, square kilometres, and square miles.

You can also enter a price per unit area to instantly calculate the total property value. Perfect for real estate, farming, landscaping, and land surveying.

Step 1: Property Information

Understanding Land Area

Area is the total surface of the land. Perimeter is the total distance around the boundary. This calculator uses standard geometric formulas and provides results in multiple units for your convenience.

Step 2: Valuation & Options

Property Valuation

Enter a price per unit area (e.g. £ per square metre or $ per square foot) to instantly calculate the total value of the land. This is useful for real estate, investment, and property assessment.

Conversion Reference

1 acre = 43,560 sq ft = 4,047 sq m = 0.4047 ha
1 hectare = 10,000 sq m = 2.471 acres = 107,639 sq ft
1 sq mile = 640 acres = 259 ha = 2.59 km²

Area & Perimeter Formulas

Rectangle: Area = length × width  |  Perimeter = 2 × (length + width)
Square: Area = side²  |  Perimeter = 4 × side
Circle: Area = π × radius²  |  Circumference = 2 × π × radius
Triangle: Area = ½ × base × height  |  Perimeter = sideA + sideB + sideC

Frequently Asked Questions

What is a territory calculator?

A territory calculator is a tool that computes the area, perimeter, and other metrics of a piece of land or property. It can handle various shapes like rectangles, squares, circles, and triangles, and convert between different units of measurement such as acres, hectares, square feet, and square metres.

How do you calculate land area?

Land area is calculated differently depending on the shape. For a rectangle, multiply length by width. For a square, square the side length. For a circle, use π × radius². For a triangle, use ½ × base × height. This calculator handles all these shapes and provides results in multiple units.

How many square feet are in an acre?

There are 43,560 square feet in one acre. This calculator automatically converts between acres, square feet, square metres, hectares, square kilometres, and square miles.

What is the formula for perimeter?

Perimeter formulas vary by shape. For a rectangle: 2 × (length + width). For a square: 4 × side. For a circle: 2 × π × radius (circumference). For a triangle: sideA + sideB + sideC. This calculator computes the perimeter for all supported shapes.

How is property value calculated?

Property value is calculated by multiplying the total area by the price per unit area. For example, if a plot is 2,000 square feet and the price is £200 per square foot, the total value would be £400,000.
