Measure your project area in length x width x depth (all in feet), then divide by 27 to convert to cubic yards. Use our Cubic Yards Calculator for accurate results with material weight estimates.
A board foot is a unit of lumber volume equal to 144 cubic inches (1 ft x 1 ft x 1 inch). Calculate it as: (Thickness x Width x Length) / 144 when all dimensions are in inches. Our Board Foot Calculator handles the math automatically.
Identify your scale ratio (like 1/4 inch = 1 foot), measure on the blueprint, then multiply by the scale factor. Our Scale Conversion Calculator supports common architectural and engineering scales.
There are 27 cubic feet in 1 cubic yard (3 ft x 3 ft x 3 ft = 27 cu ft). To convert cubic feet to cubic yards, divide by 27. Use our Cubic Feet to Cubic Yards Calculator for quick conversions.
Break the room into regular shapes (rectangles, triangles), calculate each section separately, then add them together. Our Square Footage Calculator supports multiple shape types.
Linear feet measures length only (one dimension), while square feet measures area (length x width). To convert between them, you need to know the width of your material. Use our Linear Feet to Square Feet Calculator for material planning.
