Construction Unit Converter
Quickly convert between common construction measurements.
About This Tool
When to Use This Tool
Use the Construction Unit Converter anytime you need to translate between measurement systems commonly used in the building trades — feet to meters, square feet to square yards, cubic yards to cubic feet, or pounds to kilograms. It is especially helpful when working with imported materials that use metric dimensions, reading architectural plans drawn in metric units, or ordering from suppliers who quote in different unit systems than what you are used to.
How It Works
Select a measurement category — length, area, volume, or weight — and the converter instantly translates between all common units used in construction and remodeling. It handles the conversions builders encounter most often: fractional inches to decimal inches, square footage to square yardage for carpet and flooring orders, cubic feet to cubic yards for bulk material deliveries, and weight conversions for structural load calculations.
Tips for Best Results
- Remember that carpet is usually priced per square yard (divide square feet by 9), concrete is ordered by the cubic yard (27 cubic feet per cubic yard), and roofing materials are sold by the "square" (100 square feet).
- When working with both imperial and metric plans, always convert individual dimensions before calculating areas or volumes — converting the final area or volume number directly is a common source of error because the conversion factors are squared or cubed.
- For quick mental math on the jobsite: 1 meter is roughly 3 feet 3 inches, 1 kilogram is about 2.2 pounds, and 1 cubic meter is approximately 1.3 cubic yards.
- If your plans show dimensions in millimeters (common in commercial and international projects), divide by 25.4 to get inches, or use this converter for exact results without rounding errors.
Length Converter
Feet & Inches Breakdown
Fraction ↔ Decimal Inches
9/16 = 0.5625 | 5/8 = 0.625 | 11/16 = 0.6875 | 3/4 = 0.75 | 13/16 = 0.8125 | 7/8 = 0.875 | 15/16 = 0.9375
Area Converter
Quick Coverage Reference
1 acre = 43,560 sq ft
4×8 sheet = 32 sq ft | 4×10 sheet = 40 sq ft | 4×12 sheet = 48 sq ft
1 sq yd = 9 sq ft | 1 sq m = 10.764 sq ft
Volume Converter
Quick Volume Reference
1 cubic yard concrete ≈ 2 tons
80 lb bag concrete ≈ 0.6 cu ft | 60 lb bag ≈ 0.45 cu ft
1 cubic meter = 35.31 cu ft = 1.308 cu yd
Weight Converter
Common Material Weights
Gravel ≈ 105 lb/cu ft | Lumber (pine, air dry) ≈ 35 lb/cu ft
Drywall (4×8, 1/2") ≈ 57 lb | Plywood (4×8, 3/4") ≈ 60 lb
Roofing shingles (1 square) ≈ 250–350 lb
