How to use it
- Open a calculator, such as the gravel calculator or the concrete calculator, and enter your measurements.
- Press Add to project list under the result. The line saved is the total the calculator shows, with every area and the allowance included.
- Repeat for each material. Lines for the same material are added together.
- Come back here to check the list, remove lines you no longer need, then copy it as plain text or print it.
What each total includes
Each total adds up the volume and weight of every line for that material, in cubic yards and cubic meters, and US tons and tonnes. Bags are counted once per bag size, from the combined volume, then rounded up. That is the same rule the calculators use when you add more than one area.
Costs appear only if you typed a price into the calculator. The list never adds prices, delivery or tax of its own.
