Inch profile size to a metric catalog size
Enter the size from a US drawing, in decimals or fractions such as 1/4 or 1-1/2, and see the closest F1 catalog size of the same shape.
101.6 × 101.6 × 6.35 mm
SHS 100×100×6 · 3.5 kg/m
Depth -1.6%, width -1.6%, wall -5.5% against the inch size. Check the section properties before substituting.
A metric section of nearly the same size is not automatically equivalent: check it with the FRP profile calculator or the column calculator.

Frequently asked questions
How many ksi is 1 MPa?
1 MPa = 0.1450377 ksi, and 1 ksi = 6.89476 MPa. Multiply a value in MPa by 0.1450377 to get ksi.
Which conversion factors are these?
The exact definitions 1 in = 25.4 mm and 1 lb = 0.45359237 kg, with standard gravity 9.80665 m/s² for pound-force, as listed in NIST Special Publication 811. The table rounds to four significant figures; use the converter above for full precision.
What strength does pultruded FRP have in both units?
EN 13706 E23 tensile strength: 240 MPa = 34.81 ksi; EN 13706 E17 tensile strength: 170 MPa = 24.66 ksi; E23 interlaminar shear: 25 MPa = 3.626 ksi. Values for F1 profiles are on the technical data page.
