Feet and Inches Diagonal

Processing...

The Feet and Inches Diagonal calculator computes the diagonal of a rectangular area based on the length and width. /attachments/dd0252f2-c435-11e4-a3bb-bc764e2038f2/diagonal.png Rectangular Area

INSTRUCTIONS: Choose units and enter the following:

(W) Width of Rectangle Area
(L) Length of Rectangle Area

Diagonal (D): The calculator return the length of the diagonal in feet and inches. However, this can be automatically converted to other length units (e.g. meters) via the pull-down menu.

The Math / Science

If you want square corners in your fenced area, the simplest ways is to compute the diagonal and use is when placing corner posts.

To make a fence area with square corners:

place the post in corners 1 and 2. This defines the length (l).
determine the width you wish (w)
compute the diagonal with this calculator (D)
walk off the width in approximately the right direction to make corner #2 square.
Measure the diagonal from corner #3 to corner #1.
Adjust corner #3. Move corner #3 to the left if real diagonal is too short. Move corner #3 towards the right if the real diagonal is too long. Do this unit the diagonal matches the computed value.

Fence Calculators

Number of Posts and Rails: Computes the number of fence posts and rails needed for a length of wood fencing.
Post and Rail Fence Cost Estimate : Computes material costs for post and rail fence based on the number of posts and rails (above) and unit cost pricing.
Wire Fence Materials: Computes the materials needed for a high tension fence.
Wire Fence Cost Estimate Computes the materials and costs of a high tension wire fence.
Labor Cost for Posts : Computes the approximate cost of labor in digging and setting fence posts based on the length of the fence, uniform distance between posts, method of digging (by hand, power auger) and the hourly labor pay rate (DPH).
Perimeter of a Rectangular Shaped Area computes the length of a fence perimeter in a rectangular shaped area base on the length (l) and width (w) of the area.
Diagonal of Rectangle Area computes the diagonal measurement of a rectangular area. This is useful in ensuring that your area has square corners.
Circular Fence Calc computes the diameter, number of posts, rails, perimeter and area of a circular shaped fenced area (paddock).
Fencing Needed for Circular Area computes the number of posts, number of sections, sides or panels, number of rail boards, perimeter and area of a circular shaped area (paddock) based on a diameter and length of sides (e.g., .
