**This calculator gives you,**

Waist slab (ft) = (√(Riser)^{2}
+ (Tread)^{2})

Number of Riser = Height of
stair/Riser

Number of Treads = Length
of stair/Riser

Volume of 1 step = 0.5 x
Riser x Tread x Width of stair

Volume of Total step =
Volume of 1 step x No of riser

Length of Waist Slab =
(Number of riser x Tread)

Height of Waist Slab

Slant Height of waist slab
= (√(Length of waist slab)^{2} + (Height of waist slab)^{2})

Volume of Waist slab =
Width of stair x Thickness of Waist Slab X Slant Height

Total volume of stair (cft)
= Volume of total step + Volume of waist slab

Total volume of stair (cum)
= (Volume of total step + Volume of waist slab)/35.315

Dry volume of Stair in
Cum = Volume of stair x 1.524

Dry volume of Stair in cft
= (Volume of stair x 35.315)

Cement Volume = (Dry volume
x Cement)/sum of ratio)

Cement in kgs = (cement
volume x 1440)

No of Cement Bags = (Cement
Volume/0.035)

Sand Volume in cum= (Dry
volume x Sand)/sum of ratio)

Sand Volume in cft = ((Dry
volume x Sand)/sum of ratio)) x 35.313

Sand in Kgs = (Sand Volume
x 1550)

Sand in Ton = (Sand Volume
x 1550)/1000

Aggregate Volume In cum =
(Dry volume x Aggregate)/sum of ratio)

Aggregate Volume In cft =
(Dry volume x Aggregate)/sum of ratio) x 35.313

Aggregate In Kgs =
(Aggregate Volume x 1350)

Aggregate In Ton =
(Aggregate Volume x 1350)/1000

**GENERAL****
GUIDELINES:**

1.
The respective tread and riser dimensions for all the parallel steps should be
the same on the consecutive floor of a building.

2.
The minimum vertical headroom above any step should be 2 m.

3.
Commonly, the number of risers in a flight should be restricted to twelve.

4.
The minimum width of stairs should be 850 mm, though it is desirable to have a
width between 1.1 to 1.6 m. Large stair widths should be provided in a public
buildings, cinema halls, etc.

5.
Staircase angle of inclinations should not more than 40 degrees horizontal.
