VIDEO: slope calculation in percent

Carry out a gradient calculation - that's how it works

1. To calculate the gradient in percent, you only need two values: the length of a section and the height or height difference between the beginning and the end of the section.
2. If you have obtained these values, for example by measuring, divide the height by the length.
3. The result of this division task is the uphill or downhill gradient - but not yet in percent.

The formula in a practical example

1. Over a distance of one kilometer, the path height rises to 50 meters. So the height is 50 m and the length 1000 m. It is necessary to convert both values ​​to the same unit in order to get a correct result.
2. Now divide the height by the length of the line. In the example given, the calculation would be 50 m: 1000 m.

Especially in traffic, the gradient is often given as a percentage. Find out here ...

3. Calculated results in 50 m: 1000 m = 0.05. However, this result is not yet available as a percentage. Another step is necessary for this.

Convert the result to percent

1. Calculating the gradient in percent is also very easy. All you have to do is multiply the result you received by 100.
2. In the example above, the preliminary result was 0.05. If you take 100 this time, you get 5%.
3. These 5% indicate that the height increases by five meters for every 100 meters of route length. So this is a gentle slope. It is different with a gradient of 50%. The height changes by 50 meters every 100 meters.

Of course, in nature and in road traffic there are seldom evenly rising or falling heights. The gradient in percentage is therefore mostly only an average value, but still a helpful indication.
