Round Concrete Steps Volume Calculator - Metric

The Round Concrete Steps Volume Calculator (Metric) is a tool designed to calculate the concrete volume required for round steps using metric units. This calculator is essential for construction projects requiring precise concrete volume estimates for multi-step, round stair structures. It allows you to add multiple steps, with each new step increasing in size based on the previous step's dimensions. Outputs include cubic metres and cubic yards for each step and the required total volume.

Calculator

• enter the total length of the step in metres ( the distance from one side of the step to the other along the back edge)
• the width of the step in metres (the depth of the step from the front edge toward the back)
• enter the horizontal depth (run) of the step in millimetres (this value is used to calculate the incremental overhang of each new step you add and is not used for the first step)
• enter the vertical height (rise) of the step in millimetres

Results

• volume required for the step in cubic metres
• volume needed for the step in cubic yards
• Arc Length (ft): The step length along the curve in metres
• Radius of Circle: the radius of the full circle from which the step's segment is part, measured in metres (the radius of the hypothetical complete circle that would include this segment)

Adding Additional Steps

1. Once the current step has been calculated, click Add Next Step to create a new step with adjusted dimensions.
2. The calculator automatically updates the length and width of the new step by adding the "run" value to the previous step's dimensions, creating a slight overhang.
3. Repeat the process for each additional step, filling in any adjustments for Run and Rise values if they differ from the previous step.
4. After each calculation, the calculator updates the Total Concrete Volume section.

• the total concrete volume in cubic metres
• the total concrete volume in cubic metres

Important Notes

* Editing Steps: You can modify the dimensions of the current (last) step before calculating. However, if you need to edit a previous step, click Start Over to reset the calculator and begin anew.
* Start Over Button: This button clears all steps and resets the form to its initial state, allowing you to start a new calculation.
