#### About Stair Estimator

This Calculator calculates the volume of cement, sand, and aggregate, the weight of steel rod according to percentage, Numbers of bags of cement required to construct an RCC Stair.

#### Standard Data used in this Calculator

- Added 54% extra Concrete to convert wet volume into dry volume.
- Density of cement = 1440 Kg/m
^{3} - Density of Steel rod = 7850 Kg/m
^{3} - 1 Bags of cement = 50 Kg

The above calculator helps you to calculate the total quantity of material like cement, sand, aggregate, numbers of bags of cement, Weight of steel rods, etc.

To calculate cement, sand, aggregate, numbers of bags of cement, Weight of steel rods in concrete, follow the steps below.
