Trade Guidelines for Unit Conversions & Measurement
Professional tips and standard industry assumptions for accurate material takeoffs and error-free estimating:
Metric to Imperial Multipliers
Key factors: 1 meter = 3.28084 feet; 1 square meter = 10.7639 square feet; 1 cubic meter = 1.30795 cubic yards; 1 liter = 0.264172 US gallons; 1 kilogram = 2.20462 pounds.
Tape Measure Common Fraction Decimals
Standard fractions: 1/16" = 0.0625", 1/8" = 0.125", 3/16" = 0.1875", 1/4" = 0.25", 5/16" = 0.3125", 3/8" = 0.375", 7/16" = 0.4375", 1/2" = 0.5", 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".
Paint Spreading Rate Conversion
To convert European or Australian paint coverage (m² per liter) to US coverage (sq ft per gallon), multiply m²/L by 40.746. For example, 10 m²/L equals approximately 407 sq ft per US gallon.
Acreage Dimensions
One acre equals exactly 43,560 square feet (about 208.71 feet by 208.71 feet if square), which is 4,046.86 square meters or 0.404686 hectares.
Frequently Asked Questions: Unit Conversions & Measurement
How many square feet are in one acre of land?
There are exactly 43,560 square feet in one acre. A square 1-acre parcel measures roughly 208 feet 8.5 inches on each side.
How do I convert millimeters to inches on a tape measure?
Divide millimeters by 25.4 to find decimal inches. For example, 76.2 mm ÷ 25.4 = 3.0 inches. For fractional conversions, multiply the decimal remainder by 16 for sixteenths of an inch.
How many liters are in one US liquid gallon?
One US liquid gallon contains approximately 3.78541 liters. In the UK and Commonwealth countries, an Imperial gallon is larger, containing 4.54609 liters.
How do I convert paint spreading rates between metric and imperial?
Multiply square meters per liter (m²/L) by 40.746 to get square feet per US gallon (sq ft/gal). Conversely, divide sq ft/gal by 40.746 to find m²/L. A standard 350 sq ft/gal rating equals ~8.6 m²/L.
