Angle cut calculator

Use this simple tool to accurately calculate how many degrees are in any roof pitch, stair stringer, or any other slope standard or metric.

Enter the values for the roof pitch in inches per foot rise. Then select a fraction if there is any. Strangely enough, if a pitch of 6 inches rise per foot is entered, then the degrees generated is not It takes three steps using trigonometric functions to achieve an accurate result.

For all other slopes a run must be entered. The box has a pre-defined value of 12 because rafter pitches are the primary function of this calculator. Simply click in the field inside the box and enter a value for the inches and fraction if necessary. For the complementary anglereverse the rise and run. The inches box will also accept decimal values making it possible to calculate the degrees for any slope!

For a quick reference for getting the angle of a pitch, use a speed square. Simply line up the common slope with any straight edge and see what degree it is on.

Such a saw is useful when building for example boxes with slanted sides or concrete forms for post caps. It is surprisingly complex to compute compound angle settings. On this page I have collected a few compound angle calculators that will help compute compound angles. Miter joints and butt joints have identical miter angles; only the bevel angle is different.

We can see this in the picture on the right; the cutting lines on the face of the board are parallel. Angle Precision: Choose the number of decimal digits you would like to round the angle results to.

A board with a slope in the long direction intersects a vertical post which is rotated a certain angle. An n-sided box is built from n identical side pieces and a bottom. The box can have sides that are slanted outwards.

The outward angle is the side angle. Note that this calculator also works for rectangular boxes. An n-sided pyramid is built from n identical triangular side pieces, not including the base. The base radius is the distance from the center of the pyramid's base to one of the base corners.

The height is the distance from the center of the base to the apex. The side slope is measured from horizontal and can be used to calculate any cuts needed at the bottom of the pyramid's sides. Pyramids with butted joints are some weird animals.

A few more or less realistic examples are shown on the right. A concrete form for casting post caps can be made in the shape of a pyramid.

The pyramid can have a square or rectangular base. The side slopes are measured from horizontal and can be used to calculate any cuts needed at the base of the pyramid. In the case of a concrete form, we need the inside surfaces of the form to line up. In other cases you may want the outside surfaces to line up, but given the same board thickness and a rectangular base, we cannot have both the inside and the outside surfaces line up with this model.Please provide 2 values below to calculate the other values of a right triangle.

Roots vs twin screw

Right triangles, and the relationships between their sides and angles, are the basis of trigonometry. The sides of a right triangle are commonly referred to with the variables a, b, and c, where c is the hypotenuse and a and b are the lengths of the shorter sides.

The altitude divides the original triangle into two smaller, similar triangles that are also similar to the original triangle. If all three sides of a right triangle have lengths that are integers, it is known as a Pythagorean triangle.

In a triangle of this type, the lengths of the three sides are collectively known as a Pythagorean triple. Examples include: 3, 4, 5; 5, 12, 13; 8, 15, 17, etc.

Area and perimeter of a right triangle are calculated in the same way as any other triangle. The perimeter is the sum of the three sides of the triangle and the area can be determined using the following equation:. Thus, in this type of triangle, if the length of one side and the side's corresponding angle is known, the length of the other sides can be determined using the above ratio.

Metre Meter.I recently had a woodworking project with compound angles. A quick search of the web for an online calculator quickly showed that, even though there are plenty of great miter calculators out there, I wasn't able to find to for calculate a butted joint at a compound angle. Just adjust angular orientation accordingly.

Notes on angles: Input: Slope angle is measured from the horizontal plane. Included angle refers to the angle the two pieces meet in plan view. Results: End angles are given in relation to a square end. End angle refers to the angle on the end of the piece when it is laying in the horizontal plane like on the top of a tablesaw. End angle is the angle you'd set your crosscut fence to. Bevel is given in degrees from vertical, when the piece is laying flat on a horizontal plane like on the top of a saw table.

Bevel is the angle you'd set your blade to. Butted compound angles. Butted compound angles are more complex than a simple mitered joint.

Petrochemical industry

Unlike a mitered joint where the two pieces to be joined are tipped at the same angle, in a butted joint, the two pieces to be joined can have different angles. This happens when a shallower angled piece intersects a steeper angled piece. This can be tricky to visualize when cutting -- mark your material carefully!

If it doesn't do what you want, go ahead and make your own, like this excellent page: Bjorn Jansson's Compound Miter Saw Calculator his does butted joint too! Compound Angle Calculators I recently had a woodworking project with compound angles. These two calculators were designed with a tablesaw in mind, although you could use it with any tool. Notice that the long point of the angle on the butting piece is toward the top, and the long point of the capping piece is at the bottom this is represented by the negative angle.

It doesn't actually matter which piece butts and which caps, so in the calculator, they are simply referred to as A and B.The roof pitch calculator calculates slope, pitch, angle and rafter lengths, based on input of rise M and run R. Use the diagrams on this page as a reference when inputting rise and run, and while interpreting the calculated results. To determine the finished height of the ridge beamadd the Rise M and the Y height.

To determine the Y height, measure from the bird's mouth up the calculated slope X in 12 to the top of the rafter. This is very useful information for many purposes, especially for roof framing - the slope, sometimes called pitchis calibrated on speed squares. This is useful because sometime you may need to cut a bevel with your circular saw that is not calibrated using roof pitch style - this setting on circular saws is calibrated in degrees. Rafter Length - The rafter length results, from this calculator, represents the length of line L on the diagram s.

Note that this is not the actual length of the rafter. It is the length of this portion of the rafter. If you plan to have overhang, etc.

Pitch - Is the incline of the roof represented as the ratio of rise to the span twice the run. If you are calculating rafter length from the center of the ridge beam as shown belowyou will need to subtract half of the thickness of the ridge beam from the top end of the rafter. For example, if the ridge beam is 1. For more information on roof building, cutting rafters and other design considerations, see the mycarpentry roof framing section.
