#### Calculation

1. enter the number of risers
2. the riser height of the step in inches
3. the run of the step in inches
4. the thickness (depth) of the throat in inches
5. the length of the landing in inches
6. the landing depth in inches
7. the width of the stairs in inches

#### Results

1. the total rise of the stairs in inches
2. total run of the stairs in inches
3. the slope of the stairs in degrees
4. the amount of concrete needed in cubic feet
5. the amount of concrete needed in cubic yards
6. the amount of concrete needed in cubic metres

##### Conversions
```one cubic inch (in³) = 0.000578703703703704 cubic feet (ft³)
one cubic inch (in³) = 0.0000214334705075445 cubic yards (yd³)
one cubic inch (in³) = 0.000016387064 cubic metres (m³)```

```To convert cubic feet to cubic yards multiply cubic feet * 0.037037037037037
To convert cubic feet to cubic metres multiply cubic feet * 0.028316846592
To convert cubic yards to cubic metres multiply cubic yards * 0.764554857984```

### When Ordering Concrete

This concrete calculator will help you in estimating the amount of concrete needed for your project. The amount given as needed, does not include any waste. It is recommended, depending on the job you are doing, to add anywhere from an extra 4% to 10% to your concrete order to make sure you have enough concrete to finish the job.
