Can someone explain what the % mean when hills are graded? I am a novice cycle tourist and look to embark soon

Answer 1

The grade of a hill is measured as a percentage in the United States. This is simply the slope of the hill written in percent form. For example, if you have a hill that drops 200 feet over one mile (5280 feet) the grade would be 200/5280 = 0.0379, or a 3.8% grade.

Answer 2

A grade (or gradient) is the pitch of a slope, and is often expressed as a percent tangent, or "rise over run". It is used to express the steepness of slope on a hill, stream, roof, railroad, or road, where zero indicates level (with respect to gravity) and increasing numbers correlate to more vertical inclinations.

The higher the %, the steeper the hill.

Answer 3

The % of a hill is the gain in elevation divided by the distance travelled then multiplied by 100 to turn the ratio into a percentage. For example, if a hill gains 100 feet over 1000 feet travelled, it is a 10% grade.

Answer 4

Not sure what you mean. But if you are asking about the grade (slope) of the hill expressed in percent, then a 1 percent grade would be 1 foot of rise per 100 feet of run.

Answer 5

Percent of grade is the slope angle given as a percentage, the formula is change in elevation vs. distance. An example is a 10 foot rise over a 100 foot distance, this would be a 10% grade, 20/100 would be a 20% grade. This is different than a grade given in degree's where a 100% grade (100' rise in 100') is a 45 degree angle.
