What Is This Tool?
This converter transforms magnetic flux density values from line/square inch, an obsolete CGS-based unit, into weber/square inch [Wb/in^2], a unit relating magnetic flux in webers over one square inch of area. It facilitates the updating of historical or legacy measurements into a form more compatible with modern magnetic analysis.

Tips & Best Practices
-
Ensure input values are precise since the conversion factor is very small (1e-8)
-
Use this tool to bridge legacy CGS-derived units to more modern magnetic flux density units
-
Double-check final results when dealing with historical data to account for measurement uncertainty
-
Consider further conversion to tesla if you require full SI unit compliance
-
Refer to examples and definitions to maintain clarity in magnetic flux density documentation
Limitations
-
Line/square inch is an obsolete, legacy unit which may introduce uncertainty if data is imprecise
-
Weber per square inch is still a non-SI unit; further conversion to tesla might be needed for some applications
-
Very small conversion factor requires careful attention to numerical precision in calculations
Frequently Asked Questions
-
What does line/square inch represent in magnetic units?
-
Line/square inch is a non-SI unit representing one magnetic line of flux (one maxwell) per square inch, used historically in magnetics and electrical engineering.
-
Why convert line/square inch to weber/square inch?
-
Converting enables updating obsolete CGS-based magnetic flux densities to units more compatible with modern engineering and scientific analysis.
-
Is weber/square inch an SI unit?
-
No, weber per square inch is a non-SI unit that corresponds to magnetic flux over a square inch area and relates directly to tesla, the SI unit.
Key Terminology
-
Line/square inch
-
A non-SI magnetic flux density unit equal to one magnetic line of flux per square inch; historically used in magnetics and electrical engineering.
-
Weber/square inch [Wb/in^2]
-
A unit of magnetic flux density denoting one weber of magnetic flux per square inch of area; non-SI but directly related to tesla.
-
Magnetic flux density
-
A measure of the strength of magnetic field over a given area, typically expressed in tesla, webers per square meter, or other units.
