Measuring & comfort
Measuring & conversion calculators
Most material estimates start here: the area of a room in square feet or square metres, or the volume of a hole, bed or slab in cubic yards or cubic metres. Split an odd-shaped room into rectangles, triangles and circles and the area calculator adds them up — plots come out in acres, hectares and marla too.
The unit converter changes feet and inches, square feet, cubic yards, gallons, pounds and more in one go, and the BTU calculator sizes an air conditioner for a room in BTU/h, kW and tons, with extra for hot climates.
