Msi to GPa
US data sheets give the elastic modulus of FRP, aluminum and steel in Msi (millions of psi); metric data sheets and EN 13706 use GPa. Multiply Msi by 6.894757 to get GPa.

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 GPa is 1 Msi?
1 Msi = 6.894757 GPa, and 1 GPa = 0.145038 Msi. Multiply a value in Msi by 6.894757 to get GPa.
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 modulus does pultruded FRP have in both units?
E23 lengthwise modulus: 3.336 Msi = 23 GPa; E17 lengthwise modulus: 2.466 Msi = 17 GPa; Structural steel: 29.01 Msi = 200 GPa. Values for F1 profiles are on the technical data page.
