Translating pressure sensor readout into actual pressure

I've been playing with our new analog pressure sensor and came up with the following correspondance between the actual pressure in the system, as shown by an analog pressure gauge, and the readout from the pressure sensor as an unsigned integer. According to my graphing calculator,

(actual pressure) = 6.346 * (pressure readout) + 96.05

The raw data is thusly:

Code:
actual pressure | pressure readout
0               | 102
20              | 220
40              | 346
60              | 470
80              | 611
100             | 731
Hope this is helpful! I'm curious to know if your sensor is different.
