Confusing Instructions

[deleted-84482]

I'm doing the science fair project called "The Measure of Mercury: Analyzing Impact Craters on the Innermost Planet" (https://www.sciencebuddies.org/science- ... p036.shtml). I am having trouble in the procedure section with equations 7, 8, and 9, and the steps involved in those equations. I don't understand where I am supposed to get the conversion factor from. I can get the height scaling factor and the width scaling factor fine, but am I supposed to combine those somehow to create one conversion factor for equation 9? Or am I supposed to do equation 9 twice with both the height scaling factor and the width scaling factor separately? Could someone please walk me through this?
Here is a sample of my data to use:
Image 1
Height Scaling Factor = 4.64568
Width Scaling Factor = 4.64569
Crater 1 Image 1
Diameter: 1.29259 x (This is where I get stuck).
Thank you for the help. If you have any questions, please ask by replying.

Hi Foringr,

I just replied your question in the Math/Computer Science Forum. If you have further questions, please post them there to avoid duplication.
