# MeasureFoundry > Material calculators & practical project planning ## Posts - [A five-minute material estimate check before you order](https://measurefoundry.com/material-estimate-checklist/): Before sending an order, read the estimate as if someone else had prepared it. - [Compare material quotes using the purchase unit and delivery](https://measurefoundry.com/material-quote-compare/): A fair quote comparison starts with the same required project quantity, then uses each supplier’s actual purchase unit. - [US gallons and imperial gallons are not interchangeable](https://measurefoundry.com/us-imperial-gallons/): A gallon label is incomplete unless it identifies the system. The international US liquid gallon is 3.785411784 litres. The imperial gallon is 4.54609 litres. - [Pipe capacity: internal diameter makes the difference](https://measurefoundry.com/internal-pipe-diameter/): The water-storage volume inside a full circular pipe uses its internal bore. Outside diameter includes the wall material and overstates the internal space. - [Drywall and insulation sheets: area counts are only a starting point](https://measurefoundry.com/sheet-coverage-cutting/): Dividing net area by sheet coverage gives a lower-level purchasing estimate. - [Brick estimates: use the visible face and the joint module](https://measurefoundry.com/brick-face-dimensions/): A simple wall-face estimate divides wall area by a repeating brick-and-joint module. It needs the brick face length and face height. - [In-situ excavation and loose spoil are different volumes](https://measurefoundry.com/excavation-bulking/): Soil before excavation occupies an in-situ volume. After digging, the loose material can occupy more space. - [Gravel volume to tonnes: ask for the right bulk density](https://measurefoundry.com/gravel-volume-weight/): The geometric volume of a bed comes from its area and depth. Converting that volume to a mass requires bulk density. - [Paint coverage, coats and tin size are three separate inputs](https://measurefoundry.com/paint-coverage-coats/): A spreading rate such as 10 m²/L normally describes one coat under stated conditions. Two coats over the same wall require two passes over its area. - [Paintable wall area: subtract openings once](https://measurefoundry.com/paint-area-openings/): A paint estimate needs the surface area being coated. - [Flooring estimates: keep pack coverage and room area separate](https://measurefoundry.com/flooring-pack-rounding/): A pack may contain several boards and cover a non-round area. Enter the labelled area per pack, not the area of one plank, in a pack calculator. - [How many tile boxes should you buy? Use the box coverage](https://measurefoundry.com/tile-box-coverage/): Use the coverage printed on the box when the purchase unit is a box. - [How to separate material allowance from purchase rounding](https://measurefoundry.com/choose-material-allowance/): Allowance and purchase rounding solve different problems. Allowance changes the target quantity to account for losses you choose to plan for. - [Cubic metres, cubic yards and cubic feet: a practical conversion](https://measurefoundry.com/cubic-metres-yards-feet/): Length conversion factors must be cubed when converting volume. One yard is three feet, so one cubic yard contains 27 cubic feet. - [Concrete bag weight is not the same as concrete yield](https://measurefoundry.com/concrete-bag-yield/): A bag’s mass tells you how much material you carry. Yield tells you how much mixed concrete it produces. They are different quantities. - [How to measure a rectangular concrete slab](https://measurefoundry.com/measure-concrete-slab/): Convert all three dimensions to one length unit before multiplying. Diagram is not to scale. ## Pages - [Estimate limitations](https://measurefoundry.com/disclaimer/): These tools calculate quantities and illustrative costs from your inputs. - [Terms of use](https://measurefoundry.com/terms/): Development draft — operator and jurisdiction review required before launch. - [Privacy policy](https://measurefoundry.com/privacy/): Development draft — operator and jurisdiction details need review before public launch. - [Contact & report an issue](https://measurefoundry.com/contact/): We welcome corrections and feedback on calculator usability. - [About MeasureFoundry](https://measurefoundry.com/about/): MeasureFoundry helps people turn measurements into material quantities and clearer purchase decisions. - [Material Cost Calculator](https://measurefoundry.com/material-cost-calculator/): Estimate one material line including delivery and an optional tax percentage. - [Water Tank Calculator](https://measurefoundry.com/water-tank-calculator/): Calculate rectangular tank capacity in litres, US gallons and imperial gallons. - [Pipe Volume Calculator](https://measurefoundry.com/pipe-volume-calculator/): Calculate the volume of a full circular pipe from its internal diameter. - [Brick Calculator](https://measurefoundry.com/brick-calculator/): Estimate bricks for a single wall face with editable brick dimensions and mortar joints. - [Paint Calculator](https://measurefoundry.com/paint-calculator/): Estimate paint litres and whole tins from your measured area and product coverage. - [Insulation Calculator](https://measurefoundry.com/insulation-calculator/): Convert net surface area into whole packs using the coverage on your product label. - [Drywall Calculator](https://measurefoundry.com/drywall-calculator/): Convert net surface area into whole sheets using the coverage on your product label. - [Flooring Calculator](https://measurefoundry.com/flooring-calculator/): Convert net surface area into whole packs using the coverage on your product label. - [Tile Calculator](https://measurefoundry.com/tile-calculator/): Convert net surface area into whole packs using the coverage on your product label. - [Excavation Calculator](https://measurefoundry.com/excavation-calculator/): Estimate a rectangular excavation and compare in-situ and loose spoil volume. - [Gravel Calculator](https://measurefoundry.com/gravel-calculator/): Estimate aggregate volume and mass using your supplier’s bulk density. - [Concrete Calculator](https://measurefoundry.com/concrete-calculator/): Estimate a rectangular concrete pour in cubic metres, cubic yards and cubic feet. - [Calculator categories](https://measurefoundry.com/calculator-categories/): Choose the type of project quantity you need. - [Volumes calculators](https://measurefoundry.com/volumes-calculators/) - [Surfaces calculators](https://measurefoundry.com/surfaces-calculators/) - [Masonry calculators](https://measurefoundry.com/masonry-calculators/) - [Groundwork calculators](https://measurefoundry.com/groundwork-calculators/) - [Budget calculators](https://measurefoundry.com/budget-calculators/) - [Supplier pack cost comparison](https://measurefoundry.com/supplier-comparison/): A cheaper pack is not always a cheaper order.
