I hope a message board of this caliber can help me.(adsbygoogle = window.adsbygoogle || []).push({});

Here is my problem. How does one measure a percent of grade? Specifically in a ratio or in a liner measurement how would I know what a 5% grade is? I need to ensure a field is within 5%, is that so many inches out of level in a foot, yard, or mile?

Any help would be greatly appreciated.
