Parts Per Thousand & Gradients Question

  1. Feb 7, 2012 #1
    Hello all

    I was wondering if anyone could help me with the following:-

    The equation of a line is Y = -0.00331x + 9907.333.

    The equation represents distance (x) and elevation (y)

    The gradient is -0.003311. What is number represents is for every 1 unit I move in the x plane I move -0.003311 in the y plane.

    My question is how do I convert -0.003311 into parts per thousand?

    Does part per thousand mean for every 1000 units I move in the x plane how much do I move in the y plane or does it mean for every 1000 units I move in the y plane, how much do I move in the x plane??

    Can anyone help?

    Thank you in advance
