1. Length Unit Conversion

When performing length unit conversions, the following are some common conversion relationships:

1 inch (in) = 25400 micrometers (μm) = 25.4 milpmeters (mm) = 2.54 centimeters (cm) = 0.0254 meters (m)

1 foot (ft) = 12 inches (in)

2. Pressure Unit Conversion

The pressure unit conversion relationships are as follows:

1 pound-force per square foot (psf) = 0.0069444 pound-force per square inch (psi)

1 pound-force per square foot (psf) = 0.0004882 kilogram-force per square centimeter (kgf/cm²)

1 pound-force per square foot (psf) = 4.8824274 kilogram-force per square meter (kgf/m²)

1 pound-force per square foot (psf) = 0.0004725 standard atmospheres (atm)

1 pound-force per square foot (psf) = 0.0478803 kilopascals (kpa)

3. Mass Unit Conversion

The mass unit conversion relationships are as follows:

1 pound (lb) = 0.4535924 kilograms (kg) = 453.5924 grams (g)

1 pound (lb) = 16 ounces (oz)

1 pound (lb) = 0.9071847 jin

4. Area Unit Conversion
