The definitions below gives 1 Gauss as 6.45 lines/in^2, just as JW says, and I've verified by calculation. Hope it helps.
Calculation:
From Definitions,
1 Max = 1 Line
since 1 Gauss = 1 Max/cm^2,
Simple conversion(1/cm^2 to 1/in^2) gives:
1 Gauss = 6.45lines/in^2
Definitions:
gauss (G or Gs) [1]
the CGS unit of magnetic flux density. A field of one gauss exerts, on a current-carrying conductor placed in the field, a force of 0.1 dyne per ampere of current per centimeter of conductor. One gauss represents a magnetic flux of one maxwell per square centimeter of cross-section perpendicular to the field. In SI units, one gauss equals 10-4 tesla. The unit is named for the German mathematician and astronomer Karl Friedrich Gauss (1777-1855).
maxwell (Mx)
a CGS unit of magnetic flux, equal to 10-8 weber. In a magnetic field of strength one gauss, one maxwell is the total flux across a surface of one square centimeter perpendicular to the field. This unit was formerly called the line [2]. The newer name honors the British physicist James Clerk Maxwell (1831-1879), who presented the unified theory of electromagnetism is 1864.
line (li) [2]
a former name for the maxwell, the CGS unit of magnetic flux. The unit was called the line because magnetic fields were traditionally represented by lines depicting the direction of the field; the idea was to quantify the strength of these lines. This is a small unit, so fields were often measured in megalines; one megaline is equal to 0.01 weber.

1 x C/m**2 = [4 x (pi) x 10**(-5) / sqrt(muo x epsilono)] x Lines/cm**2
and
Gauss as a Gaussian Unit for B=Magnetic Flux Density is convetible to MKS unit Weber/m**2 as
1 Weber/m** = 10**4 x Gauss
Then obviously the Maxwell as a unit of PHI=Magnetic Flux is convertible to Weber as
1 Weber = 10**8 x Maxwell
By using Lines/cm**2 related to Maxwell, there is an ambiguity introduced in units, which may be viewed objectionable.

I see this as for example using tons for weight as well as for distance, which is possible but not practical and therefore not used.
