Concrete is ordered by volume, but projects are measured in feet, inches and metres. These calculators convert your measurements into cubic yards or cubic metres and tell you how many pre-mixed bags you would need.
Each calculator lets you set a waste allowance and choose your bag size, because spillage, uneven ground and product yields vary from job to job.
