Converting Percent Grade to D:M:S
You are grading a piece of property and the site plans call for an
embankment with a grade “no steeper than 35%.” Your level shows
the slope at an 18° 15’ angle. Will this pass?

Since your level reading of 18° 15’ is less steep than 19° 17’ 24”, the
slope will pass inspection.
