How do you determine pitch of roof?
The pitch of a roof is measure in a simple way. Rise over run. By this it means that, given the standard example of a 4/12 roof ,for every 12 inches or one foot of distance or run there is an according rise of 4 inches in height. If you wish to determine this you need to know the length of the rafters and then the height from the center of the rafter to the peak of the roof. For instance if the rafters happen to be 24 feet long that means that the run is 12 ft and if the height from the bottom of the rafter to the peak is 8 feet then you have a 8/12 pitch roof.

How to compute the area to know how much tons of refrigeration is needed?
I assume your formula is based on interior square feet of building area. If the building is a rectangle or square, then the length in feet, multiplied by the width, in feet, gives you the total area, in square feet. If the building is square, the length and width are both the same length. Measure the lengths and widths in feet and tenths of feet, or if allowed, round off to the nearest foot. If you use inches, convert them to feet and tenths of feet, or if allowed, round off the tenths of feet to the nearest foot. If the building has more than four sides, draw lines inside the building, to divide the interior building shape into two or more rectangles. Calculate the area for each rectangle and add up the areas from each rectangle, to get the total square feet or total area of the building.
What is the actual rise of a roof rafter?
Depends on what pitch the roof is. Measure the ceiling joist to a point or to center and then plumb to the rafter and do the math. 3, 4, 5, x 12 pitch rises that much per foot of distance on the ceiling joist. 3x12 pitch, 12 feet to center of joist, 3x12=36. 36 inch rise from the edge of the roof to the center.

Instructions for swires roofing square?
The figures on the outer edge of the curve are degrees. Use these to set the angle/pitch of the roof. The figures on the inner edge of the curve are a ratio of the length of common rafter per foot or metre of run or span of roof. Take half the span of the roof in feet OR metres and multiply by the figure for the pitch of your roof this will give you the length of your rafter from birds mouth to the centre of the roof. Then make a deduction of half the thickness of the ridge board. at right angles to the bevel . The easiest way to use the bevels/angles from the square is to place the square on a piece of ply or board and mark all the bevels/angles onto the board and then use a sliding bevel/bevel square to apply the bevels/angles to the rafters and other members of the roof. No 1= Plumb & Seat cut for the Hip No 2=Plumb & Seatcut for Common Rafter No 3=Edge cut for the Hip (Mitre) No 4=Edge cut for Jack Rafter No 5=Side cut for Purlin No 4A=Edge cut for Purlin (Mitre) No 6 Lip cut to Purlin .This is the sloping cut which goes under the bottom edge of the Hip where the Purlin abutts to the Hip Rafter
