Construction Calculator

Reaching for a separate calculator app or a spreadsheet in the middle of an inspection slows you down. Pasco Cloud includes a purpose-built construction calculator that handles the calculations you actually need on-site — area, volume, perimeter, concrete pours, and material weights — all without leaving the platform.

What You Can Calculate

The Construction Calculator is organised into two sections: Calculators for pure geometry and Use Cases for practical construction scenarios.

Calculators

Area

Calculate the area of common shapes:

• Rectangle — length x width
• Triangle — base x height / 2
• Circle — from radius or diameter
• Trapezoid — parallel sides and height

Volume

Calculate the volume of 3D shapes:

• Rectangular prism (box) — length x width x height
• Cylinder — radius and height
• Cone — radius and height
• Sphere — from radius

Circumference & Perimeter

Calculate the linear measurement around shapes:

• Circle circumference — from radius or diameter
• Rectangle perimeter — length and width
• Triangle perimeter — three sides

Use Cases

Concrete Pour

Enter the dimensions of your pour area and get:

• Total volume in cubic metres (or cubic yards)
• Number of concrete trucks required (with configurable truck capacity)
• Breakdown by truck load

This is particularly useful for planning concrete deliveries and estimating costs before a pour day.

Material Weight

Enter dimensions and select a material to calculate the total weight:

• Density lookup for common construction materials (steel, concrete, timber, etc.)
• Results in kilograms or pounds
• Useful for lifting plans and transport logistics

How to Use It

1. Navigate to Tools → Construction Calculator from the sidebar
2. Select a calculator type from the dropdown in the sidebar (Area, Volume, Circumference/Perimeter, Concrete Pour, Material Weight)
3. Choose a shape from the vertical list in the sidebar — each shape shows an SVG diagram that helps you visualise which dimensions to enter
4. Enter your dimensions in the input fields
5. Select your preferred unit system — metric (mm, cm, m) or imperial (in, ft, yd) using the shared unit selector
6. View the results calculated instantly as you type

💡 Tip

Use the Construction Calculator while filling in reports on-site. If you are completing a concrete pour report and need to verify volumes, the calculator is one click away in the sidebar — no need to switch apps or pull out a separate calculator.

Unit Support

The calculator supports both metric and imperial units. Use the unit selector at the top of each panel to switch between systems:

Results are displayed in the appropriate unit for the calculation — square metres for area, cubic metres for volume, and so on.

Visual Diagrams

Each shape in the calculator includes an SVG diagram that illustrates the dimensions you need to enter. The diagram fills in progressively as you enter values, giving you visual confirmation that you are measuring the right thing. This is especially helpful for less common shapes like trapezoids or cones where it may not be immediately obvious which measurement goes where.

Practical Tips

• Concrete pours: always add a waste factor. The calculator gives you the theoretical volume — real pours typically need 5–10% more to account for spillage, uneven ground, and formwork variations.
• Material weight: useful for checking whether a delivery will exceed a crane's safe working load or a truck's payload capacity.
• Quick checks: use the area calculator to verify quantities in reports — if someone claims 500 m² of painting on a room that is 10 m x 8 m, the calculator quickly confirms or flags the discrepancy.

ℹ️ Did you know?

The Construction Calculator is available on both the web app and the mobile app, so you can run calculations wherever you are — at your desk or on the ground floor of a job site.
