Units Conversion

1 inch (in) = 25.4 mm
1 foot (ft) = 0.3048 m
1 pound-force (lbf) = 4.44822 N

Note: The allowable loads in the table are based on conservative ASD (Allowable Stress Design) calculations for steel with a yield strength of 36 ksi. Higher strength steel (e.g., 50 ksi) and the LRFD (Load and Resistance Factor Design) method are also common in practice.
