Gradient converter

%, percent
m/km, metre per kilometre
ft/mi, foot per mile
tan, tangens
alpha, angle (degree)
y/x, ratio length / height
m / km

The results have been rounded to significant digits.

The gradient is the ratio of the vertical to the horizontal distance (Δy/Δx, tangens). By this converter you may transform several possibilities to quantify a gradient (for example of roads) into each other.

Usage: Type the value you want to convert into the field, behind which you find the corresponding unit. Click on any free space of the window. Read the result in the unit you wish. Use the "reset" button to reset the calculation.
In the bottom line of the table you may enter a distance of your choice in km. After a mouseclick on any free space of the window, the corresponding height in m is calculated for a given gradient.

Example: What is the angle of a road with a gradient of 14 % ? Type "14" into the field, behind which you find "%". Click on any empty space of the window. Read the result in the field in front of "alpha" (about 8 degree, 7.9696°).

- Large and small numbers are written exponentially. As example 2.3e5 = 2.3⋅105 = 230000 or 4.5e-5 = 4.5⋅10-5 = 0.000045.
- There is no warranty for the conversion. Cactus2000 is not responsible for damage of any kind caused by wrong results.
- Please send an email if you have suggestions or if you would like to see more conversions to be included.

- A collection of all Cactus2000-converters running offline may be ordered for a price of € 15.-. A test version is available for download for free.
