Absolute Encoder Scaling

I have a Sick wire draw absolute encoder  (Part # BCG13-I1BM0599) The given information that I have is as follows:

- Wire Draw Absolute Encoder (wire draw mechanism and encoder together) - .001 resolution

- Encoder Total Resolution - 1073741824 counts

- Counts per revolution - 262144

- Max pull out length - 5.2 meters

  I need to scale this down to a span of 0-150 inches. If you have any advice, I would very much appreciate it as I am at my wits end. Thanks.
