I graphed Magnetic Field (T) vs Current (A) and my slope was equal to 0.0012 which is off by 10^-3. Can someone suggest why this could be happening?

I used the Magnetic field data in Gauss (I did convert it) and Current in Amperes

http://i41.tinypic.com/auic6o.jpg this is what it looks like
 
Current (A)
0.1
0.175
0.25
0.325
0.4
0.475
