10 carefully crafted calculators and tools to help you with engineering & construction

New

Area Calculator

Calculate the area of a rectangle, circle, triangle, or trapezoid. Enter dimensions in feet, metres, inches, or yards and get the area, plus the equivalent in square feet.

Area of rectangles, circles, triangles and more.
New

Board Foot Calculator

Calculate board feet from thickness, width, and length, for one piece or a batch. Add a price per board foot to estimate the total lumber cost.

Board feet and lumber cost.
New

Brick Calculator

Estimate how many bricks you need for a wall. Enter the wall dimensions or a known area, pick the brick type, and get a brick count including a waste allowance.

How many bricks a wall needs.
New

Concrete Calculator

Estimate how much concrete you need for a slab, footing, or round column. Enter your dimensions in feet and inches and get cubic yards, cubic metres, and the number of 60 lb or 80 lb bags — including a waste allowance.

Concrete volume and bags for slabs and columns.
New

Drywall Calculator

Estimate drywall sheets for a room. Enter the dimensions, choose whether to include the ceiling, deduct doors and windows, and get the sheet count with a waste allowance.

How many drywall sheets you need.
New

Gravel Calculator

Calculate how much gravel, sand, topsoil, or mulch you need. Enter your area and depth to get the volume in cubic yards and the weight in tons and pounds.

Gravel, sand, topsoil and mulch volume & weight.
New

Paint Calculator

Estimate how many litres or gallons of paint a room needs. Enter the dimensions, subtract doors and windows, choose your number of coats, and get a realistic amount — including the ceiling if you want it.

How much paint you need for a room.
New

Roof Pitch Calculator

Convert a roof's rise and run into pitch (x:12), degrees, and percentage slope. Enter your footprint to get the true roof area using the slope-factor multiplier.

Roof pitch, angle, and slope factor.
New

Tile Calculator

Estimate how many tiles and boxes you need for a floor or wall. Enter the area and tile size, add a waste allowance, and get the tile count and boxes to buy.

How many tiles and boxes you need.
New

Volume Calculator

Calculate the volume of a box, cylinder, sphere, or cone. Enter dimensions in feet, metres, inches, or yards and get the volume in cubic units, litres, and gallons.

Volume of boxes, cylinders, spheres and cones.

Accurate measurements save money and prevent costly mistakes on construction projects. CalcPool's engineering tools help you calculate material quantities, estimate concrete volumes, measure area and perimeter, and plan construction projects with confidence. Every tool supports both metric (SI) and imperial units and can be switched instantly.

Why Use CalcPool Engineering Tools?

Metric and imperial

Every engineering tool supports both metric (metres, kilograms) and imperial (feet, pounds) units. Switch between systems instantly without re-entering your data.

Practical, not theoretical

Our tools are built for real construction scenarios — not just classroom problems. Every calculation includes practical notes about waste factors, safety margins, and real-world application.

Built for professionals and DIYers

Whether you are a professional contractor estimating a large project or a homeowner planning a home improvement, these tools are designed to be useful at any scale.
