I am very new to Terragen and need to create a terrain to the scale of 30 sq meters = 1 pixel. I have tried the default terrain, "Fractal terrain 01" and varying the lead-in and smallest scale but they didn't seem to have much effect. What can I set to get a specific resolution of the world?

Terragen is real-world scale. The default planet is roughly Earth-sized.
When you say 30sq metres per pixel, are you trying to create a map? If we know what you're aiming at then we'll have a clearer idea of how to help.
Welcome btw. ;)

Thanks for the welcome and the help. I'm trying to create a terrain to replicate a flight simulator terrain. They tend to be low resolution for higher rendering speed. So, I guess it be from 30 meter dem data would be the equivalent. Maybe I was wrong with the 30 sq meters.

Ah that makes sense. If you wanted to create that look, I would try making your landscape with any of the terrain generating tools and then right at the end of your terrain nodes, have a Compute Terrain node (it should be there by default anyway) with the Gradient Patch Size set to 30. You may need to go higher, but ultimately that might help you.
